Do NOT do it!!!
I am in Texas and this plant is so extremely invasive that I have realized that if I lived here for many years an...Read Mored worked daily to rid my yard of this plant, it would never be eradicated!

It has separated boards on our storage building, which must be replaced.
It has grown between the roof and the shingles of that building.
It has shown up in every part of my yard, far from where it was planted by a prior unsuspecting owner.
The battle to just contain it is never ending.
My husband and I spent an entire day recently, digging and pulling and pulling and digging. And it will be back, in those same places, because you can NEVER get rid of the roots.
This plant can grow inches a day and will invade flower beds, yards, climb up your house and leave suckers that will not be easily removed.
Carpenter ants LOVE it and will come for the nectar and then invade your home.
I can not express how much I dislike this plant.

It is not worth the pretty little flowers to deal with YEARS of eradication after you realize just how truly invasive this vine is.

Athens GA 30606 - bought this plant to put along a fence, which DH decided against. The potted plant was placed against a towering pine ...Read Moretree ... time passed. It is absolutely lovely, has climbed 60 ft or more, and no problems with spreading beyond the (ahem) pot which remains beside the pine tree. Hummingbirds love it. Just this one time during 22 degree freeze in March 2017, vines "slid" down the tree partially, but fine with us as we now do not need binoculars to see the flowers.

We have some majestic oaks in our yard near where we planted the vine, as well as our neighbors have an oak tree directly behind the fence as well. It would be heartbreaking to have these vines take over those trees in the future. I also spent years taking out a huge blackberry in our yard...so I do not want to fight this vine either. Teaches me a lesson...research before you plant. Thanks for all of the informative info on this site. I am going to research other evergreen vines and find one that will work better in our yard.

Love these, really pretty plant native to my area that is excellent for hummingbirds but please only put them in Southeastern USA (where ...Read Morethey are native) due to their spreading habits.
They are best suited for natural landscape plantings/planting on the edges of forests unless you plan on aggressively pruning them.

A good alternative (with a wider native range) is Trumpet Honeysuckle (Lonicera sempevirens or something like that). It's native to Eastern North America and also some Western areas as well (I think Southern Alaska also has them). They are more semi-evergreen in mild climates and much smaller and mild mannered, though they do send up baby plants (after 7 years of mine I have only gotten a few/it's not a problem).

Basically, people, please research plants before making blind purchases and do not grow this plant where it is not native (due to invasive potential) and also do not grow a 'care-free' plant if you want a 'well-behaved' plant. Seriously, all of these issues would be solved if people researched before planting or, where native, if people learned to accept that not all yards have to be perfectly tidy.
These plants aren't "satan" and I'd rather have these than the tacky invasive bamboo and elephant ears everyone plants here, at least these serve a purpose.

My grandmother gave me a cutting approx. 10 years ago. We live only 30 minutes apart and have the same sandy soil with similar light and ...Read Morewater conditions. However, hers is full of flowers in the Spring and Fall and mine only gets a about 40 blooms in the Spring and even less in the Fall. Her vine is greatly neglected only getting water as nature provides and no fertilizer ever. I have tried tending to mine diligently and also neglecting it. What flowers I do get (which I am grateful for) are usually not very vibrant. I am at a loss as to how to best care for this vine, as it seems that no matter what I do, it will not bloom very much or with vibrancy. I give it a positive rating because it does bloom and feed my two hummingbirds for a brief period and I'm sure that if I knew what I am doing wrong and corrected that , it would be a more beautiful plant. Plus, my grandmother's vine is absolutely gorgeous(the mother plant).

For over twenty years, the vine took over my mother's driveway and grew into the neighbor's trees, but never bloomed. A garden service p...Read Moreulled all the vines off the trees and back into my mother's yard, and they did get rid of it by digging up the roots and maybe used chemicals, but they also loaded wood mulch over the area and that seemed to smother it. This was a one-time treatment. I took a root of it and planted it in the center of my yard where I would be lawn mowing quite a bit around it. Some spouts came up in the grass, but I snip them with scissors and place a funnel at the snippets and pour either boiling water from a kettle or white or cider vinegar. I do that about three times a year. That way only the suckers of the vine is damaged and not the grass. And, I always pull the pods off the vines before they split open. After about five years, my vine finally bloomed. I had it grow on a metal laundry poll and the roots actually seemed to grow into the metal and wrapped around and around to a height of about twelve feet, creating a beautiful canopy at the top. One year a squirrel made its nest smack dab in the center of it on top. When it bloomed, hummingbirds came and sometimes a butterfly or two. The hummingbirds come around 5 in the evening and leave just before sunset. With all the aggravation of this vine, sitting in my lawn chair, before the mosquitoes come eat me, watching the hummingbirds as they flit into the flowers then rest on a branch of the vine stopping to look at me, is peaceful and wonderful. A little mouse lives at its base and even that makes me happy. I live in a house in Cleveland, Ohio, within a 50'x150' lot, and to see hummingbirds frequent is an unexpected urban sight. Last year, bats came and seemed to fly especially more around the top of the blooming trumpet vine. They arrived this year as well. I knew the plant could have a negative impact, but it's worth it.

Trumpet vine is not killed by either Roundup or a broadleaf killer. The most that it will do is burn part of the roots closest to the app...Read Morelication. The remaining roots will resurface. Roots however need the sunlight and that is the key. If you can put chickens in that area they will kill the emerging trumpet vine shoots and eventually the entire plant. Without chickens you have no choice but to dig up the new shoots and apply Roundup to the root. Eventually you will win the battle.

This kitchen is more than 12 feet from the base of the plant, yet, it goes under my deck, into my foundation and up into the house. So I'm not sure that even the photosynthesis suggestion is completely valid. It travels more than 25 ft into my vegetable raised beds even. It's an ongoing battle and if anyone ever comes up with something to kill it, I WANT TO KNOW ABOUT IT. For now it's digging everywhere I can and round-upping where I can't. You have been warned.

Note the propagation methods. Birds are great propagators.
Trumpet Vine can send underground roots for at least 30 (thirty) feet. If it climbs a tree, it will eventually kill it, the same as wild grape vines.

I picked one up in the store and when pulling it out of its bag, it looked not just dead, but dead-dead with shrivelled roots. Dormant roots do not look like this. I put it in the ground anyway. Maybe I can later change my neutral to positive.

I do not have neighbors to worry about except those who grow too much corn and kill everything else. Even so, there is plenty of space between where I want the plant and the property line.

Wow… hard to believe how much Trumpet Vine is out of control in our gardens, but since the stores keep selling it, we'll have to keep d...Read Moreealing with it. The unsuccessful use of RoundUp can be attributed to their mechanism: they are over-dosing plants with growth hormones - kind of like giving them a triple speedball of meth and heroine. Maybe it will kill them, maybe not.

So here's what worked for me in Southeastern Pennsylvania:

1) Pick up some ground clearing agent in concentrated form. It's critical to be concentrated, so go to a local garden supply and see what professional strength product you can score. I used Trioxx years ago, full strength, but I don't know if it's still on the market.

2) Cut off the branch back to an area thick enough that you can drill a deep half inch hole into it from the end, positioned so you can get it to hold liquid (so, not a horizontal branch). Closer to the trunk is better, but not too far from a lot of branching.
You cut off the outlying foliage so that birds and bees don't eat poison taking into the vine's system.

3) Drill down as far as possible, at least 1.5 inches, preferably more. Do this on as many branches as practicable.

NOW, PUT ON YOUR DISPOSABLE, PLASTIC GLOVES.

4) Using a small syringe which you will throw away, inject concentrate into the holes, and immediately go onto Step 5. Remember, this is strong stuff and if you spill it on the ground, it can be taken up by anything in a 3-4 foot radius enough to kill it and will last for 2-3 years.

5) Wrap some duct tape around the wound to seal it off from evaporation, inquisitive hands, rain splashing/drawing it out, etc. You can also use 2 layers of plastic wrap and rubber bands.

Repeat Steps 3-5 in as many places as you can. It is especially helpful to do this near, but not on, the ground where the trunk is the largest, in several places, without having to cut stuff off down to that level.

Of course, this would be best to do in the active growth season, perhaps on a nice hot day in July or August so the plant is already stressed.

6) Be a good citizen: Burn the cuttings where you won't inhalf the vapors, and so they don't take up living in a compost pile somewhere after City collection of yard waste.

7) For any little suckers, spray them every day or two with a systemic like RoundUp (I prefer other brands) for a period of at least one week, then dig them up. This will leave the ground safe for other plantings.

It's a lot of work, but I think it's less destructive and frustrating than calling in the Apache choppers to scorch out a winning in the ground battle.

Yes, it's a bad idea to grow it next to a "good neighbor" fence, but it's easier and less brutal to deal with than a thorny bougainvillea...Read More that grows with similar carefree abandon (and gives you a nasty reaction if the thorns happen to scrape or poke you!).

Despite the plant's reputation, if you want to draw in hummingbirds, Campsis radicans (Trumpet Creepers) are great choice for native plan...Read Moret aficionados. There nectar is the equivalent of 'crystal meth' to them. The bloom time is 2-3 months in the SE and they're not that hard to control, if you stay on top of them or plant them in the right place. I once had to hit a few stragglers w/ Roundup but otherwise they definitely have a place in my native southern garden.

If you prefer an earlier blooming vine in the same family try planting Bignonia capreolata (Crossvine). It has a much shorter blooming period, but unlike the Trumpet Creeper it retains much of it's foliage in milder climates where the leaves can turn burgundy if grown in full sun.

I'm giving it a thumbs up, but with caveats:

-D0 NOT ever plant it anywhere near a neighbor's property.
-DO NOT e...Read Morever locate it anywhere near other plants you water and/or feed.
-DO NOT water it after it is established. Never, ever feed it.
-DO plant it where it is forced to closely complete with other natives.
-DO prune it often and hard, but not too close to the ground. Leave 8-10 inches standing; otherwise it will produce even more "suckers" than normal. Wear heavyweight gloves, a heavyweight shirt or jacket, and cover the lower part of your face with a bandana or scarf - just in case you're allergic. I don't know if I am or not, but it's a chance I don't want to take. :) If the reaction is anything like the one I have to poison ivy - well, I don't want to go there. Wash everything in hot water and detergent afterward, and clean your pruners with soap and alcohol.

Mine is on a woodland verge with lots of other natives, getting about two hours of direct sunlight a day, and it stays under control. YMMV.

...Read More
I, too, love the blossoms and the way it attracts hummingbirds and butterflies. For many years it was on my list of plants I desperately wanted to have someday.

After a mere 3 months of dealing with the neighbor's trumpet vine on a common back fence, I thank the powers that be every day that I never managed to plant it anywhere, leaving a problem behind me to trouble and dismay former neighbors and new tenants.

We are in a desert climate. We are renting a home where the previous owner had laid down 30' of astroturf, black plastic, and rock in lieu of having an actual yard. If I owned this property instead of renting, I would want to xeriscape the back yard and make it a liveable place - but because of the trumpet vine, I would not be able to.

This thing has sent shoots out 30 and 40' from the mother plant, across the hellscape of rock, plastic, and astroturf, to come up in the sole plantable spot in the yard, a 3' wide bed around the edges of the patio into which are planted mostly roses. And the vine repeatedly comes up in the roses, which it is damaging and slowly killing in the inadvertent protection provided by the rose's very own thorns.

It hasn't managed to come up through the astroturf itself, but it is coming up through the black plastic and rocks in its hundreds, and I do mean HUNDREDS, of small vines.

These vines unfortunately do not stay small. No, they grow at the speed of light. One day there's a couple of leaves - the next time you look out the back door and it and a dozen brothers have grown halfway up the side of your shed already.

When you go pull them down, the tough rootlets rip shreds away from the siding on said shed. Said shed shredded. Trust me, it is nowhere near as funny as it sounds.

You can't dig them up with out removing all the plastic and rocks. Pulling them up has strained my shoulders more than once, and is often impossible. Cutting them off as far back as you can manage only encourages them.

I called the extension agency to find out how to kill the thing, and they told me - suggested a 2,4 D herbicide. Then they told me I am not allowed to use it to kill the sprouts in my yard because it will kill the mother plant as well. I am tempted to do it anyway and hope that the neighbor thinks the desert finally claimed the horrid thing, but I suspect they'd just plant another, or - worse yet and my greatest fear - it wouldn't actually kill the mother plant, it would just make it angry and out for revenge.

The extension agent was TOTALLY unsympathetic to my plight and kept telling me it is NOT invasive. I soon found out why. She has planted this monstrosity herself, which was making her irrationally defensive of it.

She thinks it won't grow in the desert unless you water it - this thing is not watered by me OR by my neighbor, it is 60 or 70' up a hill from their back door.

Then she accused me of being complicit in its spread because I had allegedly altered the "natural balance" of this desert environment by "introducing water".

I don't know about anyone else - perhaps its just me - but does anybody out there water astroturf, or large expanses of black plastic covered with rocks? And how is introducing Trumpet vine to the desert not ALSO altering the desert environment? So it seems to me that having planted it in her yard, KNOWING that her neighbors are likely to be watering their back yards, she should also know full well that the proviso about it not being invasive in a desert environment no longer applies.

(And no, I do not powerwash my astroturf. I wouldn't HAVE astroturf if I weren't a renter, and I wouldn't remove it now for fear of the trumpet vine. So I do not water the astroturf, I actually take a shop vac to it.)

I swear, if there is a hell, there ought to be a special place in it for people who plant Trumpet vine KNOWING how invasive it is, leaving elderly and disabled neighbors totally at its mercy.

Please don't plant this vine. NOWHERE. Not even in Alaska should this vine ever be planted. I wonder if it would winterkill even in Siberia. There is no "root barrier" you could put down that would keep it from invading your neighbor's yard, or even coming up somewhere unfortunate in your own yard.

It is a beautiful flower. It attracts hummingbirds and butterflies like mad. But you would have to be crazy or cruel to risk inflicting this invasive weed - its official designation by the USDA - on your neighbors or future tenants of your own property.

Please plant something, ANYTHING, else. Cardinal climber. Native honeysuckle. Cleome. There are LOTS of flower, shrubs and vines that attract hummers and butterflies, and yet which won't send out 50' to 100' long runners to ruin your neighbors health and peace of mind.

I beg of you. DO NOT PLANT TRUMPET VINE.

I bought a house three years ago, not realizing the neighbor behind me had recently planted this booby trap about 2-3 years prior. Two summers ago, I noticed this plant was draping over the fence in my back yard and was starting to drop pods. I picked them up and cut the plant back to their side of the fence.

Last summer, it started climbing up a storage shed about 4 feet away from the fence, and I found several shooters springing up in the yard. Pulling the shooters off of the shed resulted in paint coming off WITH the branches, which acted like they were glued onto the shed. Luckily, I plan on tearing the shed down anyway, so I'm not concerned about that. I frankly don't care how "pretty" the plant looks, it will be getting poisoned. At this point, I'm just trying to decide whether to use the strongest herbicide in combination with gasoline and vinegar, or whether I use a small thermo-nuclear explosive... I'm pretty sure the nuclear fallout would be less of a pain than this plant.

For the love of God, DO NOT PLANT THIS. This plant CANNOT be controlled and it will destroy your neighbor's yards. It should be illegal to even sell this plant, let alone plant it in an urban setting.

BUT... the plant is now in its 8th-9th year, and is RELENTLESSLY SPREADING, UNDERGROUND, POPPING UP EVERYWHERE, 20', 30', 50', 70' away from the handsome-and-neatly-maintained main tree/trunk. Let the nightmare begin! While we did pull the occasional random sprouters in years prior, it's evident there were a lot more out of our sight, and that they've been multiplying & running farther & farther underground, and now the armies of strong vines are emerging en mass in our vegetable garden, among neighboring shrubs, out past our property into unmaintained woods. [i repeat, ALL FROM ONE WELL-MAINTAINED TREE-TRUNK] Maybe in a mowing area, the runners can be maintained? I doubt it though, I'll bet you they just run further, staying underground, away from the mower and into some other area where they can safely surface & thrive. Unfortunately, without experiencing it first-hand, people often can't appreciate the utter DISBELIEF AND FRUSTRATION (aka: how did this get all the way over here, oh my gosh there's so many, ugh and they don't want to come out) that an invasive (aka: nearly uncontrollable) plant can cause and all the TIME, DILIGENCE & LABOR it requires to get a landscape back to something manageable, something you enjoy, you know back to the "joy" of gardening.

Since the front door is back from the front wall, it grew back into the area where the front door is. The screen is a wrought iron frame, the vine is working hard to cover that with my encouragement. When it starts to hang out into the open air, I wrap it around and tuck it into the iron works. Most would call it invasive but I love this plant. It grows where I can’t get anything else to grow. It does draw in the butterflies and bees, I don’t have a problem with either. It’s working on climbing a metal garden bench/trellis, and I hope to keep circling the vine until the bench is covered. I’ve collected the seeds, which I hope will take root in the front yard, the only thing that seems to grow out there is weeds, and as much as I like this plant, I hope it takes over.

Ironically it did most of its growing when it was the hottest and driest. I went and bought another one. I also got one for my mom since she has a long railing she wants it to grow on. The first year I only got one bushel of blooms, but now I have multiple. I hope it grows over my roof because I have some ANNOYING pigeons I want the trumpet vine to choke out.

When the new owners bought her house I gave them instructions on the care of the vine. I visited the my grandmother's old house a few years ago after moving back to Texas and they still have the same trumpet vine with no problems.

Had to put neutral due to lack of experience with this. I wanted to plant this soooo bad! It's drop dead gorgeous, has lovely foliage and...Read More is a plant that is supposed to be wonderful for hummingbirds and have some herbal use as well. So I bought seeds and there are a dozen or more under my growing lights as I sit here. I understand the positive comments but was seriously impacted by the negative ones ( I always wondered why it was called cow itch vine). So here I make my solemn vow. I promise to dump everyone of those little devils into the trash as soon as I am done typing, Amen!

For those struggling to control Trumpet Vine, you can use Tordon RTU. Whenever you cut off a sprout or vine, apply the liquid liberally ...Read Moreto the stump. It's best in the fall as the plant is storing nutrients and will carry the herbicide down into the roots for an effective kill. You do need to be careful about other nearby woody plants as it will damage them too if you get it near their roots. It will not harm grasses.
Tordon RTU is a premixed version of Tordon 22K and is legal for home use in the United States. (Tordon 22K requires a license for purchase.)
Tordon will work much better than Roundup on woody plants.

This plant is indeed invasive!!!!

Invasive is the operative word. Living in a mobile home park, my now deceased neighbor had a trellis installed on our property line for ...Read Moreprivacy, you guessed it, the garden center planted a trumpet vine. FF several years and the neighbor passed on, the new neighbor now has a "healthy" trumpet vine he says he's trying to control. I made the mistake of "pruning it back" in June (he told the police I "attacked" his trumpet vine) and it promptly thanked me with lush vegetation, blooms, and more runners now appearing throughout my yard, on the other side of my home, to the point I pointed my landlord to your website to learn about what a potential problem they have on their hands. We are in our sixties, one way or the other won't be here either of us and they will have a "benign thug" to deal with taking over this part of a well kept, inexpensive mobile home park.
I blogged on to add Zanesville, OH. to the list of places "founded" by the trumpet vine - and add my corroboration to both pros and cons.

It takes 3-4 years for it to mature to the point of producing bloom, and another year or 3 before it starts to spread. Keep that in mind...Read More when reading of other's experiences who say that it is easy to control or they have had no problem.

BUT the vines are very strong and heavy, and will invade and damage structures within 20 feet and farther --like into crawl spaces, under siding, pavement and patios. Including those of your neighbors.

Cold weather does not "control" it. I have sprouts after a winter with temps to -20F, years after the main plant was cut down.

The roots are extremely strong --they start tiny and develop into arm-sized aggressive spreaders 2-3 feet underground. The more you cut or dig out the visible sprouts, the farther and more widely the roots will go looking for a hospitable spot. It may appear to be controlled by mowing and pruning but the underground spread is continuing and increasing. Any individual root segment will continue to grow, even if never allowed to produce above ground growth (ie cutting down any sprout within a day or two of appearing).

I am in my 4th year of fighting it over a 20 foot radius from the original plant. When a sprout appears I dig down (2 to 3 feet!) to expose as much of the the main root as I can manage, cut it out and apply brush-b-gone to the soil to try to catch any connecting roots. Invariably there are branches that I don't see that survive beyond the die-off -- seems it doesn't absorb or carry the poison far beyond the point of appication-- and continue the aggression.

I would only plant this (in ground) in a metal container, with drain holes covered with fine strong metal mesh, and then only far away from any desirable structure or other landscaping . It still might be able to break through that over time. Then you must also prune off any seed pods.

UPDATED 2014: I thought that I had won my battle with it last year when I found only one little sprout early and destroyed it and the root beneath. Alas, this past month I discovered 3 healthy sprouts in various spots. For the record, this is now 7 years after I destroyed the original planting and all roots (spreading up to 20 feet away) that I could find, digging up a large garden bed in the process.

I have pruned them back hard every spring and - since the bloom on new growth - get lots of flowers. My only seemingly unique comment is that - on the same root stock - on the same stem - there will be bright red flowers and also brilliant purple ones at the same time. No nurseryman or our landscapers have seen anything like it - it's really beautiful in full bloom. Have any of you heard of this before?

Another problem I see is trumpet vine starts pop up everywhere from the rizomes being underground. I just keep cutting them off and have resigned myself to this little chore being part of having the vine. I got my vine on a back road growing on a pole and the rest, as they say, is history! LOL It covers a pergola very well along with my Lady Banks rose and provides wonderful shade and brown thrushes and cardinals make their nests every year there, so all in all, it has its usefulness.

I will admit it can spread, but it is no worse than the passion vine. I think, from reading the comments, that it may be like the mesquit...Read Moree tree which is native here, but can be invasive. I learned that if you cut a mesquite tree down, it has buds under the soil which then sprout making a single trunk tree into four or five. Farmers swear that a mixture of diesel fuel and remedy will kill mesquites. You have to have a pesticide license to buy some of these things and they are expensive. You might check with your county extension agent as to how to eliminate the plant if you don't like it. It also takes three or four years to bloom and there are new cultivars which are not so invasive and have larger flowers.

Regarding the use of Round-Up - perhaps something in the Armory that is stronger that this could be tried? What else
can be utilised verses e.g. Japanese Knotweed in the USA ? We also use Picloram ( " Tordon 22K" ), Triclopyr
( " Garlon 4 " ) & 2,4-D ( In a mixture with Picloram "Atladox HI " or Triclopyr & Dicamba "Broadshot ")
Imazapyr (" Arsenal " / " Chopper" /"Assault " has been withdrawn in the UK but may be o.k. to still buy in the USA ) and there is also Sodium chlorate.

Over here, as well as Glyphosate ("Roundup") - the pesticides Clopyralid ( "Transline" by Dow ) is used against
Giant Hogweed. That might act on that Trumpet vine, I dunno.
You may not be able to get some or all of those in the USA
these days, - but I think they are all stronger than Roundup/Glyphosate.
You may have to ask the proffessional herbicide companys;- these chemicals may not be available on the U.S domestic market .

I bought a home in South Texas which had trumpet vine well established along the fence of the...Read More back yard. It was impossible to tell how old it was, but the fence was densely covered and it had entirely overtaken a telephone pole, with vines traveling both directions along the wires. There was evidence of it having been removed from the garage prior to my owning the property. The vine was cracking my swimming pool 20 feet from the fence. I thought I could cut it back and co-exist with it while I reclaimed the part of the garden where it was sprouting.

How wrong I was.This plant is a thug.

I tried Round-up. Nothing. I cut it and tried to dig it out. I discovered roots as thick as my forearm zigzagging everywhere and as deep as 3 feet. For all I know, it could have been deeper, but that was as far as I was willing to go.
I dug a deep trench both sides of the fence and wherever I could tease the main roots out, I'd cut them but leave about a foot of root sticking up above ground and then I'd apply stump killer. Every week, I'd cut away the dead section until I got to healthy tissue and reapply.

It was war for a year: digging, spraying and repeated applications of stump killer. I had to delay the installing the garden while this went on. Finally a year and a half ago, I went ahead and planted. The garden looks great.

Yesterday I found sprouts coming up in the patio bricks.
Do yourself and everyone else a favor, especially in a mild climate, plant a different vine.

After 15 years of growing this without allergic incident, my husband and I were simultaneously assaulted with a hideous attack of itching after we pruned and chipped up branches, both woody and soft growth. The chipper bag itself continued to cause itching and was repeatedly rinsed and even soaked to remove the allergens.

Although it blooms attractively, placement of this vine on your property should be carefully considered. Nothing of value should be near it as it will swamp over everything like a thick green wave.

PLEASE don't plant this unbelievably invasive plant! I planted this at my old house against the light pole and when I found it remo...Read Moreved one day I was angry. Now I realize that whoever took it away did me a big favor!

When I moved into my current house I planted another one next to my new pole. The first year it did little. When it grew high enough to arch over it began to bloom - profusely. I found out that it was the talk of the neighborhood and that everyone admired it. Then one spring I discovered to my dismay that it had suddenly sprouted volunteers around my front lawn. The roots had gone under the sidewalk. The day after every weekly cutting it would already be sticking up over the grass. I tried pulling them out but they broke off at the soil line and would sprout up shortly after and were angling toward my boxwood from both sides.

At the same time as the vine was spreading, my house was invaded by ants, not just outside by inside. They were swarming all over my kitchen and in my refrigerator. I called an exterminator and he said it was the worst infestation he had ever seen. He wanted a lot of money to fix the problem. I removed as much of the original plant as I could, had a landscaper pull out as much of the thick, traveling root as he could, and have sprayed every resurgence with roundup on a daily basis ever since. Also the ants are gone from the house without the exterminator.

Recently I visited my next door neighbor who told me that she had snatched seed pods from the plant and showed me one growing in her yard. I told her why I removed the lovely vine and asked if I could dig hers up, but she declined. I hope I'm not fighting this plant to the end of my days.

I have two trumpet vines growing along my privacy fence. I've never had a problem with either of them over the past ten years or so. Su...Read Morere, they sprout a bit from the root system but this has never been a problem. Those sprouts get mowed or occasionally pulled and by fall they stop growing back.

If you've ever had a black locust cut down, you've probably experienced very aggressive growth from the remaining root system -- sometimes sending up a dozen or two new trees, but the trumpet vine doesn't even compare . . . though the vine itself is pretty zesty when it comes to growing, the offshoots are minimal. Still, like a lot of plants, it requires some measure of maintenance. If you don't want to mess with it, then it's probably not for you.

Personally, I feel the rewards of this vine outweigh the menial amount of work it requires.

For example, the vine provides excellent privacy . . . if allowed to grow. The vines can become bushy, tall, and thick with leaves and flowers. It's a very, very attractive vine, very lush, and the hummingbirds would probably agree. The vine flowers constantly through the summer and fall seasons, and lots of flowers means lots of hummingbirds. Also, it's native to my area, though I've never actually seen one in the wild, so it's a good feeling knowing that I'm helping to both restore and provide a natural native habitat for the lifeforms at large.

My suggeation is to use the same method we did to erradicate Bamboo. Cut to root level, cover with black plastic, weigh down [ we used ro...Read Morecks], leave on for 2 years. The plant needs light to grow!

We liked the occasional color on this vine and had four Crossvines planted by the fence in our backyard. It grows well in the Dallas area...Read More and requires occasional trimming. I never had any problem with suckers or spreading until I replaced our fence and decided to eliminate the crossvines. I first cut them off and left the stumps. I decide to dig out the root on one of them - a big mistake. It was a big contorted mass, but I thought I had pretty much gotten it out. Wrong! After a couple months, I saw several vines come up a few feet away back in the pool equipment area. Then as the summer progressed, they came up everywhere - in the lawn, the landskaping, further and further away. I finally resorted to RoundUp, but they keep coming back. I found this forum hoping to find a solution. From what I read here, the solution seems to be to sell the house and move to another place. The plants that I did not try to remove the root have sent out some new shoots, but not as agressively as the one where I did.

I live in southwestern Ontario, Canada. About 15 years ago I received a flyer in the mail about this vine. The pictures showed a gorgeo...Read Moreus plant with beautiful flowers and I though this would be a wonderful addition to our backyard along our wooden fence. I bought two and when they arrived in the mail, they looked like dead sticks of wood. I complained and the company sent me two more. I never imagined these 4 dead looking sticks of wood would have grown into the monster they are today!

This vine has become a nightmare! While iy provided privacy and produced beautiful flowers every summer, we have had to trim it 3 to 4 times every summer because it is drawn toward our house, the roof, the eaves and facia. It has even started shooting out from the siding of our garage. The endless shoots sprouting up all over the yard develop roots very quickly that are hard to pull out. The hotter the temperature, the faster this vine grows. I am convinced it can grow 2 or 3 feet in one day!

After a strong wind earlier in the spring, the entire top of this vine that stretched along our fence toppled over. We cut it all down to the base and hoped this would stop any future sprouts. No, this thing just keeps sprouting new shoots everywhere. It's also been growing in the crawl space of a new addition we put on our house and shooting up between the siding on the base of the addition.

We drilled holes in the stumps and poured salt thinking this would kill the main trunk, and killing the roots. No, still growing shoots.

Today we noticed some small areas in our ashphalt driveway heaving. When we removed the top piece of ashphalt, there were several shoot trying to come up through the ashpalt!

I've read round up does not work either. Today, we got desperate enough to pour a little bit of gas into the holes of the base. Years ago, that was something farmers used to get rid of unwanted growth. I'm not advocating this at all, but when you get desparate to get rid of this very destructive vine, we had to try something different.

If this doesn't work, we will dig up around the base and try to remove as much as possible and pour hot white vinegar and salt into the area.

If I had known this plant was so invasive, destructive and so much work, I would have grown morning glories!

If you have a farm with a fence row several hundred feet away, that would be the only option I would suggest for anyone to plant a trumpet vine.

Good luck to the others who are trying to kill of this growing machine, it doesn't go easy.

I have had THREE landscaping people come out to take care of it and hundreds of dollars later it is NO better! HELP! Not to mention I broke out in a horrible rash from it! Ha, it just keeps giving!

I do have one problem though. I've tried digging up and transplanting outgrowth from runners at the base of the plant and last year I bought and planted a 3 foot high trumpet vine. Non of them have taken. All of them shrivel and die within a month or two. I watered everyday the first three days then slowly cut back the watering depending on the heat of the day, usually two to three times a week. The first few weeks I would shade them from afternoon sun. Three weeks after planting I would fertilize once with either Miracle Grow or liquid fish meal. We have clay desert soil but when planted I would dig a two foot by one foot hole filling with planting soil. I understand clay soil doesn't drain well so I tried to limit the amount of water to one gallon every watering. Any tips?

My dad would cut it back completely every three years. It started to send runners out into our border and we would rip them up but then we realized about 4 years ago that it keeps throwing them out further and further and you cannot actually rip it out. If you leave just an inch of root it will continue to grow. I have spent the last 4 years trying to get rid of it and it is still growing!!! Last year we completely tore out our 10 ft by 25 ft border (shrubs, flowers, trees, trumpet vine) and then covered it with a thick layer of card board and then mulched it 4 inches deep and it still grew under that and found the light and popped up every where! This year I completely spaded the border and foot deep and pulled out every little root I saw, it took me 3 weeks of work several hours every day to do that. Five overflowing wheel barrow fulls of roots from this one vine I dug from the ground and it is still popping up! It is in my grass too, so that means it will just grow back into my border.

I have nothing but positive comments on the Red Trumpet Vine. On my property, it is leaning on a wooden fence/wall, growing between a roc...Read Morek retaining wall and the cement driveway. It has been there for decades, get a regular winter pruning, and comes back like regular in the late spring. It is not invasive in this area or at least in my yard. The only exception is the occasional sprout a few feet away, but they're very wimpy shoots I can pull out. I think it gets there from me being careless about clippings in the late fall/winter.

The hummingbirds and honeybees love it. I like providing for he wildlife. Plus, it contrasts nicely with the deep blue/purple hydrangea bush right below it. PLUS, the neighbor's lilac hibiscus shrub also attracts hummingbirds. I think it's not invasive if it is placed properly.

I gave it a positive rating mainly because the Hummingbirds LOVE it! It also makes a good privacy screen.....my neighbor's house on the west side sits very close to mine. It has since worked it's way from my house near the front of the property almost to the back, (in a northerly direction) about 150', but hasn't tried to grow along the fence in the other direct, for some strange reason. It blooms all winter here and becomes a huge mass of bright orange color.

I am one of those who react badly to this plant, but only if I get all up in it and prune a bunch of it. It apparently is a reaction that I developed over time because the first time it happened was several yrs. into living here and I'd pruned it numerous times before this. But this one time I'd been pruning it for about an hour when I suddenly broke out in hives all over my body, even the bottoms of my feet!!.....and I also had trouble breathing. I almost had to call 911 but the benadryl finally kicked in and it subsided.

I have not had near the trouble with this plant that others have reported.....it hasn't tried to come up or grow anywhere but along the fence for me. It does need a good heavy pruning, done in the spring after it quits blooming. A few yrs. ago I tried to get one growing on the east side, outside of my kitchen window, so I could watch the Hummers while doing dishes! It got a lot of shade there though, and never did much growing or blooming. I left it there for 3 or 4 yrs. and finally pulled it up.....by then it had sent out some runners maybe 7-10' from the main plant but I pulled them up at the same time and never saw any more of it. My back yard is wide open so it would be easy for it to spread outwards but it hasn't. After reading all the previous negative reports, I would think I'm talking about a different plant.....but it looks EXACTLY like all the pictures. Maybe I just happened to get one that minds it's manners?....lol!

Although the flowers are beautiful and attract hummingbirds, it's actually more like something from a science fiction movie. Obviously, this should never have been planted where it is on our property. It has completely invaded garden areas and lawn that are 15-20 feet from the main plant, whose vines are like a solid tree trunk. Within the last couple of years we've realized that we're in trouble with this thing, and now after reading notes from others I'm worried that we'll be unable to kill it. There is no way to stay on top of the constant cutting back of the multiple shoots and vines that appear everywhere. I appreciated reading advice from other gardeners about how to try to get rid of this invasive vine which we plan to do ASAP. It even thrives despite our harsh winters. My best advice is to never plant one of these, as it has a life of its own!

Has anyone any experience in the north with this plant? The variety, or cultivar, is "Madame Galen". Any advice, suggestions as to what to do? Thanks so much! Dara

I am doing the Trumpet Vine dance for sure...it just popped up 3 yrs ago all by itself along my back fence.

It has wrapped itself around itself about 3 or 4 times and looks quite good from afar. It seemed to be under control the first few years but NOW OH NO! It is popping up everywhere and ruining our wooden fence by spreading through the spaces. My husband thinks it's pretty. But he isn't out there cutting it back and cutting it back and cutting it back! This is the summer it has decided to take over North Dallas. I have noticed a number of seedlings popping up in my yard now..they are difficult to uproot so I generally just cut them down. But I have beautiful crepe myrtles in my along my fence and I am very afraid it will kill them. I suppose I will order some of that vine killer off the internet as someone else did and drill holes into the base of it. It is really huge and I have cut it back to a type of canopy..really pretty but scary at the same time.

In VT, it's not native at all. Here in IL, it is native in many counties but not in the one where I live. If the seeds get blown into the next county, it is then invasive even by that definition.

We tried digging it up but after a three foot trench around the house and endless 1' by 6" inch tubers and roots of it that we yanked out with MUCH work we gave up. There is still more of this creature spreading its tenticles around my gardens. I have planted heather and russian sage and other invasives and am hoping to choke out the vine. Err!!!

This is my first post on DG, and I must admit to really appreciating the wisdom and the wacky humor of DGers!!!

As far as ...Read MoreCampsis Radicans grows, here are my thoughts:
- I planted a (bought) vine on the west side of a second story deck as I wanted to create summer shade over the doors/windows. 3 years later, it's still barely 5 feet over the railing.
- That's OK, as the narrow evergreens are starting to come up over the railing for the shade issue, but I must admit to loving the hummingbirds that now grace the deck!
- There are no suckers, or anything at the base. Maybe our winters are the controlling factor (we are 30 miles south of Lake Erie, in northwest PA).
- On the other hand, a neighbor has a vine that crawls up to the 3rd story each summer and never blooms.

I actually love the vine but I have had it for three years and it has never bloomed!

Two little comments I'd like to make to comments I've read here:
1) Please consider using a natural plant killer instead of Round...Read More-up or any other chemicals that are bad for the environment. Salt pellets, such as used in water softeners, work wonders. Dig up as much of the "mother" plant's root system as you can, then put the salt in there. It will travel through the root system and kill of much of the original plant. It will actually kill anything it touches so be careful to place the salt away from plants you want to keep. For hardy plants, a second treatment is sometimes required.

2) Regarding the alternative recipe suggestion for hummingbird feeders, please consider using raw sugar rather than white sugar. The reason sugar is white is because it's bleached - yes, bleach, as is chlorine - which is as bad for birds as it is for people and the environment.

Thanks,
Just another tree-hugger :-)

From reading many of your bad experiences with this potentially nasty invader. may I suggest trying Campsis grandiflora 'Morning Calm. I ...Read Morehave one here in Japan zone 9, it is far less invasive than most other trumpet vines and flowers orange pink from late May to
early October. Like most vines it requires good firm support and
regular pruning. Prefers a neutral or slightly acidic soil, best in full sun or partial shade. It has never self propagated from seed in my garden, that I am aware of but if you weed on a regular basis as I do then perhaps you'd never know. I do hope this is helpful to those of you that love
the flowers but hate the habit!

This palnt looks so good in pictures but i don't think i'm going to grow it know since it's so invasive.

I planted a trumpet vine between a wall and a sidewalk about 7 years ago and trained it up and over the edge of the garage roof and over ...Read Moremy arched doorway. People often stop on the street to say how pretty it is. It attracts hummingbirds as they pass through in spring and fall.

In my area it blooms from Feb.-Nov. When the leaves fall off, I prune it back a little so it isn't spreading across the roof. I have found that it is not interested in going under the shingles; because of the lack of light, I guess. It does like to attach itself to the painted eaves, but it can be pulled away easily. Any remaining holdfasts can be lightly sanded and painted over and it looks as if they were never there. Last year it made its way under the sidewalk and began putting up shoots in the yard. I mow/mulch them along with the grass.

All in all, I love trumpet vine for its beauty and hardiness. I haven't found it to be too invasive to deal with.

When we bought our current home I was so excited to see the vines on the chain link fence, now a year later I am sick because of the dama...Read Morege they have done to the fence and my neighbors garage. The vine has knocked the caps off the base posts at the corners of the fence, it has created much damage just to the fencing structure itself. My neighbor took a chain saw and cut the vine back to the top of our fence, a month later and the vine is back on his garage roof and into the soffits! As beautiful as the flowers are it is the most invasive plant I have every dealt with. It has taken over my back yard and am now finding shoots 300 feet away. My neighbor and I will be cutting this beast down during the winter and in the early spring will be digging in my garden to find the roots and will give them a boost of weed killer. Of course we will have to put the fence back together, too! I may try replanting this beast in a contained pot and see what happens. It is beautiful!

We are renters in a house with a large trumpet vine "tree" on a chain link fence. For the people that say it is hard to get it to grow o...Read Morer that it is easy to keep on top of, I really feel that it must be a relatively new plant (ie. younger than five years old). I say this because it seems that while the beginning life of this plant seems no problem and then easy to keep on top of - eventually it becomes a darn hydra! Every time you cut off one root, eight more spring up in its place!!! I have now found serious (in other words bigger than my husband's thumb!) sprouts on the opposite side of my house from the darn plant. It gets everywhere. It is in BOTH of my neighbor's yards and I spend at least one to two hours EVERY week hacking away at the various sprouts that pop up everywhere. I often need to bring a small hack saw to get the "root" cut back and that is not the real root - I can't even find that! I spray it with the strongest stuff I can find at Home Depot and it laughs at me. I am a little nervous now when I hear leaves rustling at night and often check on my children expecting to find trumpet vine sprouting up in their bed. They are seriously trying to take over the world and are winning. In all seriousness, no matter what you think about it being easy at first, once it really gets a foothold you will never win. It will conquer your yard, house, and neighborhood. Please think at least five times before even thinking about buying this thing. And then buy something else. Kudzu would be preferable to this stuff!!

Wow, I thought it was just me! We first purchased this plant to use as a screen for very high lattice under a deck. I was drawn to it spe...Read Morecifically because it supposedly attracts hummers. In the 2 years we lived at that house, it spread but not so that I realized how invasive it would become. We built a new house and turned that house into rental property. Not realizing the invasive qualities of the plant, I again allowed my husband to buy a couple more and use them to run on an arbor over a swing. By the time we had lived in the new house a couple years, I began fighting the battle. Pulling up runners, dosing it with roundup, cutting it back severly with hedge clippers. My husband never acknowledged my fight. We have since sold both houses. When we went back to the 1st house after our tenants moved out, I was astounded by the aggressive growth of that original plant. It had killed a bank of junipers, ran under the stairwell down the bank, was coming up between, around and over the stairs and invaded the roses and shrubs on the opposite side. I cut it back as best I could and we sold the house. We have also sold the new house, moved to a new area and recruited a landscape designer, one of her questions was 'what plant(s) do you not like?". I only had 1 to say NO to: the trumpet vine! What a legacy I have left for those 2 poor unsuspecting homeowners.

I am trying to rid my yard of this awful plant. It's a curse on the garden. It was planted at my house somewhere between 1958 and 1965 so...Read More "Audrey" is older and more established than I am. I'm not sure if I will win this battle.

It traveled under my solid cement front stoop. It is growing in 8 places right now. Considering it's been around so long I think it's been taking tips from terrorist supporting countries that build their base camps near schools with children. Every place it comes up is next to a plant I can't bear to harm. (my two old roses, and some very healthy azaleas)

Please, anyone thinking of planting this weed - Stop!

Those beetles tried to destroy my rose bushes last year and the last thing I want to do is attract them with little orange calling cards. Thankfully it's just beginning to grow and is only about 12" high. After reading the rest of the plant file information on this plant, I'm truly regretting the day I bought it. When I get home from work tomorrow, I'm going to dig it up, put it in a garbage bag, add some weed killer, throw it away and hope I caught it before it got a stronghold on my garden.

So we did that and now they're a treat to have.
Our house used to be a horse corral and so we have these iron pipe fences around our property. In the back are these two vines, all by their lonesome, and that's how they like to be. Yes, these vines are invasive, so keep one step ahead of them. If you are adamant about having one of these vines, please plant it in a nice secluded area, away from neighboring trees and your house or other wall (unless you'd like to have it grow there). That's why I am putting a positive on this plant because we have them planted so that they are by themselves and can do what they want. They also make a great privacy screen and that's what my husband and I are shooting for. Sadly, they do beckon ants. But I've never seen so many hummingbirds around as I did last year when they were in full bloom. Smell good too.
As far as rashiness...I was all over in them last year and I came away clean (but maybe that's just me). So just be careful where you plant and keep 'em pruned.

When I had mine before I moved, it crawled up a big pine tree, too, like someone else here mentions. It was absolutely beautiful.

If it is as invasive as suggested by some, I think I'd recommend planting it in a container sunken into the soil. I do that with a lot of my plants.

The original plants are located over 150 feet at the south end of my block in a line of cedar trees. In my twenty-year nightmarish battle with this tenacious invasive I have seen it come up between the concrete and foundation of the neighbor's garage apartment, crack the concrete and cinderblock retaining wall around the outdoor storm cellar, and the roots have cracked both the walls and floor of the outdoor storm cellar. I have replaced the fence along the alley twice. I have had to take out two mature trees. This year I will most likely lose my 9 foot tall, twenty year old Damascus roses to it because the vines have been coming up at the roots and strangling them. My eight foot Midas Touch succumbed last year. The vines haven't come up in my Don Juans, but it's only a matter of time.
And the roots apparently go down to China.

As for the hummers...1 part white sugar to 4 parts water, boil 15 minutes. Do NOT add red food coloring. Replace every 2 to 3 days. They love it.

Unfortunately it spread rampantly to the grassy areas and started growing into the siding of the house, causing damage on removal. It also looks very messy sprawling over the bank.

I keep cutting it back but it keeps coming up. The spread of this plant is over 500 square feet. Last year I tried to dig out the root that went towards the house, following a shoot into the ground. I gave up when I got two feet down and still hadn't found the main root.

Last week I sprayed every part I could see with poison ivy killer. I plan to repeat at weekly intervals two more times, then cover the whole thing with black landscape fabric for a season before planting ornamentals.

I would not recommend the plant at all. It spreads even more effectively than poison ivy. It is the single most invasive plant I've ever dealt with. If it's bees, butterflies or hummingbirds you want, there are so many better and more manageable choices to bring them in. If you feel you must plant this vine anyway, take extreme measure to control the spread. I would recommend a 2+ foot deep physical barrier to discourage the roots from spreading.

TRUMPET VINE CAN PENETRATE ASPHALT DRIVEWAY!!!

My neighbor, who has since moved, planted a trumpet vine 6 yrs. ago on our ...Read Moreproperty line. It was placed about 2 feet from my cement driveway. Her intentions were to attract hummingbirds. That's nice, I thought.

Anyway, my cement driveway was cracking so I had it removed and replaced with a new asphalt driveway about 7 months ago.

To my dismay, 3 days ago my wife found a 10" long shoot from this trumpet vine that had pushed itself right up through the new asphalt. It left the asphalt looking like a mini volcano had erupted from it. So much for the nice new driveway look.

I dug around the host plants base to see if I could remove the vine but main root seems to be disappearing under the new driveway. Nice, huh? To top it off, the vine seems like it’s heading in the direction of our brand new addition.

I really didn't know anything about this beast so I scoured the Internet for some insight. What I found were many first hand accounts describing the aggressive/ destructive nature of this Beast.

* Spreads up to 40-50 ft from host plant
* Strangles plants, trees
* Invades gardens, robbing them of nutrients
* Ants love this plant
* Crawls up houses and gets under siding. Rips gutters from house
* Causes skin irritation in some cases
* Many, many more negatives

This research has led me to two conclusions. First, this plant should not be sold without explicit written instructions as to where it should be planted to reduce potential damage to their the purchasers and others property. (I never would have thought it could punch a hole up and through asphalt)

Secondly, local governments should enact zoning laws prohibiting this vine to be planted anywhere close (at least 50 ft) to another’s property.

I'm sure my ex-neighbor didn't realize what a Pandora's box this would turn out to be but she's gone now and I'm stuck with the problem. If she were provided with detailed information about the veins destructive tendencies I would bet she would not have selected it.

I have not read anywhere on the web that this vine could penetrate asphalt driveways so I thought I'd let all of you know of just how aggressive this innocent looking plant can be.

If you're thinking about planting this near your house or someone else's property, you’d better think twice about it. This vine is NOT WORTH IT. There are different vines out there to choose from that don't cause anywhere as much havoc and destruction.

If you already planted it near something you care about whether it be the house, shed, tree, whatever, I'd suggest that you kill the vein before it's too late. The longer you wait, the more it spreads and the more difficult it will be to kill.

I purchased 2 vine control products to hopefully get rid of this thing.
Vine-X ® Vine & Brush Control, and Roundup® Poison Ivy & Tough Brush Killer Plus Concentrate.

The battle lines have been drawn and this war has begun. Kill the Beast!

While I understand everyones frustration with this plant. I must point out that C. radicans is a native of the American southeast. If yo...Read Moreu are a gardener like myself who enjoys natives and trys to keep them in your garden as much as possible, all you need to do is FIND THE CORRECT PLACE. Give Trumpet Vine a more isolated location in you landscape, where their invasiveness will be less of a problem. They work well to cover the base of large oak and pine trees in my landscape and lack of sun does not slow them down. It is very drought tolerant and quite self sufficient . I have to say that the beauty of a C. radicans blanketing the branches of my trees and filling my yard with butterflies, hummers and other birds is worth the little extra effort in maintaining it and keeping it in check.
It should be noted that the Tacoma radicans is an error in taxonomy due to the similarity in flower form of the 2 species. Tacoma as a Genus generally refers to a bush with yellow , sherbet orange or hot pink trumpet shaped flower nearly identical to Campis without asute observation. Tacoma is commonly refered to as "Esperanza."

While I would be very careful with this plant, even here in Zone 5, I was surprised to see that Frank Lloyd Wright had used it at Falling...Read More Water in the late 1930's. The better use was in 5' diameter planters on one of the terraces. It was in the ground by the bridge over the creek too, but the soil at the site is very thin so the usual underground spreading is limited. They used Wisteria up at the guest house. I am sure the gardeners were instructed to handle both of them pretty fiercely.

I'd go for a big planter with serious trellising in full sun and prune hard to keep it within bounds and remove all seedpods before they open. Mature plants bloom on new wood so any damage frost or your pruning might do is unlikely to prevent blooming.

I made the mistake 17 years ago planting one of these... no problems until a neighbor planted some also.. they then began producing seeds...Read More and coming up everywhere... now they have these tremendous runners that come up everywhere. I spent 3 years trying to kill them...

I have finally had success!

I no longer scream when I see one coming up, I just grin because I know I can kill it. One main trunk does try to send up sprouts each year ... I spray it and walk away.. next day, dead.. and it does not try again for a LOOOOONG time! Here is a pic of the two products I bought and mixed together... I use a little over 1 1/2 times full strength of each mixed in a spray bottle ... careful... it will kill anything it comes in contact with. I use a plastic glove on one hand and cut new sprouts in my grass in that hand and gently spray and rub on the leaves. Then just walk away... it will be dead the next day without damaging the surrounding grass or plants. I did have a big vine come up in a bush... gently pulled it out onto the grass... laid layers of newspapers under it... sprayed it... let dry and took the papers away.. it was dead the next day and just cut it at the base a few days later. some really established ones will take a few sprayings but we finally have control of the monster and it is very easy to maintain the little ones that come up... one squirt and gone!

I trim it back to the trellis each fall, and it is one of the earliest plants to green up in our yard.

Oh my gosh, what can I say that hasn't already been said. We purchased the acre next door to us from an older man that spent hours & hour...Read Mores in his yard. I had seen the trumpet vines bloom a few times over the years, but never knew how intrusive THEY were until we began trying to weed out some of them. The man literally had vines that he purposely hung by wire covered with water hose thru trees, across roofs, under/over porches, everywhere! This past weekend we attempted to cut some from a tree that is dying from this vine. We got a lot of it out by climbing up in the tree some and pulling, and then decided to go for the base of the vine. This root at the ground level is about (I am not kidding) as big around as someone's waist and goes from this tree to 4 of five others, even to the next door neighbor's trees - we had to get the chain-saw to cut it and several other "runners" in two. This vine starting weeping a STEADY drip of clear liquid. I didn't think that much about it at the time, thinking it would stop. We continued our business. Five days later, I went over to check and see how it looked. (I felt sorry for it) This thing is still dripping a STEADY drip. There is a puddle under the end of the vine, and it is trying to heal itself. I became worried that the liquid might be toxic to our cats or other animals if they drank it, so yesterday, I covered the end of it tightly with a plastic bag and taped it over. In the meantime, I have discovered numerous other vines, though not so big, everywhere in the yard, and it is trying to invade my vegetable garden. I cannot imagine wanting to plant this thing on purpose. It only blooms every few years and it kills BIG healthy trees....and takes over everything in it's path.

As a professional landscaper, it is possible although not easy to eradicate. Round-up will work it you can spray at the right time of year (after foliage is about a month or two old with no flowers yet) There must be enough foliage to spray;
you must spray enough foliage to equal the root mass of the plant. If to little foliage, the roots will not absorb enough of the chemical. For the organic hippies out there, it is also possible to eradicate a mature plant with out round-up. To do this, you must innitially remove ALL above-ground vegetation. Then every week for the next 2 or 3 growing seasons, you must remove ALL root or stem shoots. Eventually, the root system will run out of energy. If you wait too long in-between visits and the leaves unfurl, the plant will have a chance to replenish energy to its root system. Physical removal MUST be done every week.

I saw a beautiful specimen in No. California when I lived there. It was amazing and wonderful.

My mother had this growing...Read More in her yard, but it never bloomed (shade). She warned that I really had to WANT this plant if I took some. She said "beware, don't say I didn't warn you."

I found volunteers all over her back patio area, so I took some and I've planted it along my chain link fence.

They have bloomed in less than 3 years. I pruned it back hard during a fluke warm day we had recently.

So far, I don't have runners. I've caught it trying a couple of times. I plan on "spading" around the base of each this spring to prevent long underground runners. (as recommended by someone on this forum!)

I've ordered a yellow variety for an area that has horrific clay soils in a remote area.

I've found it to be well mannered, SO FAR. Although, I saw what it did in my mothers patio area.

Ok, I want to report some success in killing trumpet vine. I had a rather insidious one that was very well established growing up a tree...Read More in my yard. Yes, the flowers (way way up in the tree) were lovely but the suckers in my bedding and yard were a nightmare. I searched the web for a "kill method" and tried several, including soaking the suckers in pure RoundUp (which the plant actually seemed to like). I finally happened upon a product called Vine-X on the web. I was understandably skeptical but desparate for a solution. None of my local garden shops carried it so I ordered it online. Because my vine had about a 2 inch diameter stem, I ordered the large stem version. You apply it with a brush and I did two fairly heavy applications about 10 days apart to the stem as low as I could reach to as high as I could reach. I expected to need to reapply in the spring as my application was during a typically dormant (November) season. Good news is that so far, so good. The vine appears dead and is actually falling of the tree. So far, no suckers, which is a miracle to me, in and of itself. Just a suggestion for those who are as desparate as I was for a solution. Don't know if it would work for everyone but it did for me.

Trumpet Vine, Trumpet Creeper, Cow-Itch Vine Campsis radicans is native to Texas and other States.

I planted two of these vines on either side of my driveway on my carport roof support. On the plus side hummingbirds really seem to like...Read More them. On the negative side, they are usually full of ants. My husband and daughter hate them because unless trimmed they stick out into the carport and scratch up the cars. Once trimmed, they seem to bush out even worse. One of the vines has climbed up a tree next to the carport and is about 20 feet high. I have shoots coming up on the other side of yard about 10 feet from the original vine. I do like the vine, I just wish I had planted it somewhere else!

My husband and I saw this plant when we were on our honeymoon. They have it planted at the Biltmore in Ashville, NC. We thought that it...Read More was beautiful. After we bought our house, I found it at a local nursery. We planted it at the corner of our house in the fall, it was just a little stick with a root. By the end of the next summer we had a beautiful vine growing along side our house. Three summers later, it was flowering. We pruned it every spring and fall. We started noticing that it was sprouting up in the flower bed and then the front yard. It was climbing up under the front porch roof. We were trimming it monthly along with mowing it down in the grass. Two weeks after cutting sprouts down in the garden it would be growing again. Last spring we cut the whole thing down to about a foot off the ground. My husband drilled holes in the top of the trunk and we filled it with stump killer. The stump pulled out a couple of weeks later and we thought that it was done with. I think that it was actually worse last summer than anyother year. Our neighbor has one growing on the side of his fence in the back. We didn't know that he had one when we bought ours. We were not having trouble with it at the time. Now it is growing through the fence and under the fence. It is growing up through weedcloth and 4 inches of mulch in our childrens play area. The vines creep along the ground and root themselves into the mulch if not cut. It is growing up in the hedges in the neighbor on the opposite side of us. We are planning on digging up the front flower beds and using vegetation killer on everything because it is growing up in the plants that are there. We are also digging up the mulch in the play area and spraying that area, putting 4 layers of weed cloth and replacing the mulch with playground stones. It is a beautiful plant but not worth the labor and money to get rid of it, if you can.

My husband and I purchased our trumpet vine in hopes of hiding the ugly power pole that our energy company was kind enough to put in our ...Read Moreyard, right next to our driveway. I have very MINIMAL pruning and am thrilled with the beauty of the blooms along with all the birds and butterflies it attracts. I have asked my neighbors if it in anyway bothers them and have received no negative responses. After 8 years, our vine is about 20 feet tall and I would not think of destroying it. The birds love to hide in the leaves all summer and it gives them a place to sit while waiting for their turn at the feeders.

I will celebrate the day that it becomes illegal to sell or plant this vine. Yes, it is pretty in flower, but there are other much prett...Read Moreier vines that are just as attractive to butterflies and hummingbirds (non-invasive honeysuckle cultivars, for instance).

For anyone who plants this and would rate it a positive, I really hope you checked with all your neighbors and they feel as enthusiastic about it as you do. My neighbors have one 5 feet from our property line, near our vegetable plot. It shoots under the ground and pops up everywhere, growing several feet in a matter of weeks. Pulling them is nearly useless, because they just pop right back up. Birds carry the seeds all over, so I even have them growing on the opposite side of my 1/3 acre yard.

Hours of my annual gardening time are spent trying to keep this vine in check. I have tried high concentrations of herbicide to no avail. Even a thick layer of heavy black plastic doesn't stop it. Someday if the world is destroyed by nuclear war and every other living thing is dead, I am quite certain that there will STILL be trumpet vine thriving in my yard.

So, please, do yourself and your neighbor a favor and DO NOT PLANT THIS HORRIBLE WEED!

This thing is worse that poison oak if you pull on the fuzzy trunks of these vines when trying to remove it (not sure if the leaves will get you as well) If you see a thick fuzzy vine (usually 1/4" to 3/4" wide, but sometimes more) and it is very tightly attached to a pine or other tree, in such a way that it would be difficult to pry it off of the tree (like it has hundreds of "fingers" that grip the bark on the back side), then WATCH out. We clear a lot of brush here in Alabama, and I hate this thing worse that poison oak! Did I mention that I HATE this vine?

A neighbor planted this in their backyard. It slowly creeped up into my backyard. The flowers are wonderful and we attract lots of bees and hummingbirds. Recently, the vine has filled up several trees and the branches are now hanging down low enough for my dog to pull on them. They started to block my star jasmine from getting sun so I decided to trim it back a bit.

I was on my roof adjusting my antenna and noticed how far this vine had spread. It looks like it is in about 6 backyards. This makes for a great privacy plant, but I'm afraid it's going to kill everything in my backyard soon. I have not noticed any runners at all, but I'm keeping my eye out.

I read a few comments on here about the trumpet vine never blooming for them. This plant has no problem here. It has been blooming for about 9 months straight now. It's not uncommon for my tomato plants to produce through December, so we'll see if this vine can stick it out for a full year!!

I prefer to use a term I read on a web site which is pro-trumpet creeper (for the sake of the humming birds): trumpet creeper is "rambunctious."

I am somewhat ambivalent about this plant, but give it a "positive" because I think it is a nice native plant that is misunderstood and mis-used.

I have lived with trumpet creeper for the past twenty years. We inherited well-established trumpet creeper from the previous owners of our home on a little over an acre in Zone 9a (Nature Coast of Florida). Much of that timeframe(while I was working full time, raising my children, going to school...) our property was neglected, and the trumpet creeper was left to its own devices.

Wandering: Our trumpet creeper has worked its way from our back yard to the neighbor's five-acre parcel, where it has climbed up some 60-70' pines. It has also climbed up our oaks of varying sizes, and has practically draped several areas of our property as it has worked its way westward mostly, and I am now finding shoots at least 75 feet from the original vine.

Recently I was sitting outside on my doorstoop in the early morning, sipping on hot coffee, and watching a virtual humming bird war overhead, as the birds swooped from vine to vine, all in full bright-red bloom (our vines have always bloomed profusely). I had read somewhere that killing or eradicating trumpet creeper is a little bit like throwing the baby out with the bath water, and that made sense to me. So, I have decided to make peace with our trumpet creeper and try to rein it in, but I do not intend to kill it all or eradicate it; I merely intend to put it back in its place. I do not believe it will be an impossible effort based on the headway I have made so far.

I have cleared some areas that have been draped with overgrowth from our trumpet creeper (and other vines) to find the effort not very tedious or time-consuming. Several hours and a pile of vines later, the area is cleared, and plants that were underneath seem to be alive and in good shape, some even thriving. Having witnessed the resilience of this amazing plant, I do not put the pile of cut vines anywhere near our compost pile, neither do I leave them untended on the ground for long: I promptly burn them!

A lawn mower definitely helps with keeping new shoots cut back. Yes, they will resprout from the roots, but each time seem to be smaller, closer to the ground: I may do more to get rid of these shoots when I have time. The lawn mower is a quick and effective, albeit temporary control.

The vines which have climbed up and lived on our 50-foot or more tall oak these past two decades do not seem to have done the oak any damage at all. The vines that made their way to our concrete block house and started to climb up the walls came off easily but had done damage to the paint. Where the vines have climbed up a tree I do not want them in, I have been able to cut them off close to the base, pull on the vine, and it comes right down with little stress or strain: it does not wrap round and round the base it is growing on like some invasive vines (like air potato) do. Of course, measures have to be taken to keep the roots from regrowing: heavy mulch, herbicide, digging up the roots...

This is a plant that can -- and does -- propagate itself at least four or five different ways: seeds, runners, air layering, layering...

As for skin irritations: I have worked with it with short sleeves and my bare hands and have never noticed any skin irritation from doing so, but then I do not suffer from allergies as a rule.

Recently, I have opened a registered nursery, and I do intend to sell this vine with careful information and instructions about how to handle it and manage it. Trumpet creeper I have potted so far is behaving nicely. Like a spirited child, trumpet creeper, properly managed, is an exciting asset. I would rather have my world with some trumpet creeper in it than not. My five-year-old granddaughter, who along with her siblings and mom lives with me, calls trumpet creeper blooms "honey flowers" and she delights in sipping the nectar from the base of every one she can reach, which is not nearly as many as she would like!

If you elect to plant trumpet creeper, do so with delight: just don't turn your back on it for too long.

All your comments have alarmed me, as I am also fighting with invasive bamboo that no one told me some one had planted a number of years ago; previous owner had just kept chopping it down so that it was not visible.
Will now work to try to remove this vine before it can cause any more problems. Hopefully I have a chance since it has not been in the ground to long(don't snicker).
If I find something that helps kill it I will pass it on to the rest of you who are at your wits end.
Good luck to the rest of you.

I don't think I have ever hated anything so much in my life more than this invasive plant (except for the war in Iraq).

I wanted one of these for my hummingbird garden collection. Even after reading all the negative ratings, I recently purchased one. I just...Read More bought an iron arbor to grow it on. I am hoping this will be sturdy enough to support this heavy vine. I got an idea from another forum to plant it in a five gallon bucket with the bottom cut out. They mentioned that it typically sends out shoots from the side not the bottom. So it should help keep it under control. It needs to be heavily pruned annually to control growth. If you are concerned about damage, it shouldn't be planted near trees, houses or on anything that it can't be controlled by pruning. It has been known to take down trees and walls. I do have to disagree with the comments that it is invasive. I know every one's definition of invasive is different. To me a native plant can't be invasive and this is a native. I purchased mine at the New England Wild Flower Society Garden in the woods in Framingham, MA. They only sell natives and are very against invasive plants and would not sell it if it was. In my mind an invasive plant is, a non-native plant that contributes to the extinction of native plants. Such as the case with japanese honeysuckle. I think very aggressive would be a better discription. I also know that they will not bloom if they do not get full sun, or if the plant is too young. I think the soonest they'll bloom is at 3 and up to 5 years old. So that might be why so many people have not seen them bloom. If they are trying to eradicate it, maybe they only have plants that are less than 3 years old. I am giving it a neutral because I haven't planted it yet. Who knows I might regret planting this years from now, but I am hoping for the best. After reading another post about this being a native invasive not an exotic invasive I feel the need to post the definition of invasive as defined by the NEWFS: Invasive species – a non-native (adventitious) species that is capable of moving aggressively into a habitat and monopolizing resources such as light, nutrients, water, and space to the detriment of other species.

Trumpet Vine experience in Zone 9a, Citrus County, FL

Invasive? Yes. Beautiful? Absolutely.

If you're into ...Read Moresculptured landscapes and well-tended gardens, DON'T plant this, unless you are ready to put lots of time into making it behave. However, if you're like me, and you just love the beautiful colors & the hummingbirds it attracts, and you don't mind the natural, untamed look, and you have an area, away from structures you don't want torn down, then I'd say 'Go for it!'

I had purchased several plants some years ago (I'm thinking 3 or 4). I planted one at the base of a pine tree in my front yard. This one has managed to grow about 10-12' up the tree, and I've only discovered one underground 'runner' coming off of it. As yet, this one has never bloomed, and really seems like it is struggling. However, I had planted a second one in another area of the property. I had combined it with some of the 'native' vines that grow unchecked here in zone 9a, like Pepper Vine. I'd used metal conduit to create a 'teepee' for the vines to cover, intending it to become a vine-covered mound, which I hoped would attract wildlife & birds. Well, it definitely did become a vine-covered mound, although the Trumpet vine had not yet bloomed on it. About 6-8 months ago, darling hubby, out doing his 'yard work', decided the area needed to be cleaned up, and thinking it was just a pile of weeds, tore it all down and mowed the area. LOL...now the Trumpet Vine has found its way to an area about 30' away, and has happily made its home in neighboring palm trees and all along the ground in the vicinity. It literally has covered an area of at least 15'x15'. Much to my delight, I discovered that it is blooming this year too!! I've got to remember to thank hubby! :)

Now, I know where I'll be putting in the other vines I was planning to add for the hummers. I can't wait to see all off them come into bloom!

I don't even nip the runners...I just shove them under the mound and they add themselves to the mound.

Last year we had to dig the sucker out of the area surrounding the waste out-flow pipe where it knotted roots into the pipe to get nutrients and water. This year the remnants have shot up and I am concerned that the pipe will be blocked again soon since we are having another drought this year.

Removing the vine from the house has helped us control sweet seeking ants that previously invaded without ceasing.

I have dug up around the foundation of the house and brought up root sections 1.5 to 2 inches in diameter. I left the hole open to see what might show up. Sure enough, sprouts, full on, with long tendrils and leaves where present within three days of our seeming massacre. Now it feels like a losing game to find *any* more segments and get them out.

This was a great mature plant - plenty of seed pods, beautiful blooms and thick leafy shade around our east facing windows. Previous owners placed well thought out trellis across windows to really use the shade. I am sorry to try to eradicate it but last year's bill for pipe work convinced me. Further, the gutters, roofing tile and window frames were being systematically pried away from the house by the vine. We still have not gotten all the woody remnants off the house.

I welcome any suggestions for slowing or terminating growth of the remaining root knuckles that are exposed. (I just can't dig up any more of the yard or Sweetie will be really sad with me.) We have lots of other great plants and have a 'chem-free' operation going.

My Trumpet Vine behaved well for 40 years, covering a chain link fence and screening out the neighbors. Occasional shoots in the lawn were controlled by regular mowing. The past few years it has gone ballistic, springing up all over. Most of the shoots are coming up from (I am not exaggerating) a four foot deep pile of willow mulch. Tough plant. I am desperate enough to try a commercial Brush Be Gone product, hoping to control the new shoots. I realize it may take several applications. Although I am strictly organic, it seems an herbicide is my only hope of real control. I would not recommend this plant to other gardeners as the dang thing tends to run amok. Try Butterfly Bush for Hummers and butterflies instead, and perhaps a clematis or climbing rose to cover a fence.

To add insult to injury, the vine has never bloomed, and is heavy and destructive to the trellis. If I was the litigious type, I'd even consider suing the garden center that allowed me to purchase it with nary a word of warning. Stay away from this plant!!!

I have 2 new young plants that seem to be growing.
I'm unhappy that the old plant is dead, it is part of the character of the house. I wish it would take over my hillside, instead I have a horrible viney weed that doesn't bloom and is killing my ivy.

VERY INVASIVE. I bought this plant in a one gallon container about three or four years ago. It was blooming when I bought and has ne...Read Morever bloomed again. I planted it near a dogwood tree. It has grown to the top of the tree. There are vines all over that side of my yard. Yes, they do grow very rapidly. I am pulling up most of them, but feel it will spring up somewhere else. I was disappointed the first couple of years that it didn't bloom. Now I am more disappointed that is hasn't bloomed and I can't get rid of it. I thought of giving a piece to my neighbor, then decided they might not be my friend after a couple of years of this invading their yard. It is almost as bad as the virginia creeper that grows wild and nothing kills it.

My first apartment had a trumpet vine in the back yard and I vowed to have one in my own yard someday. I planted one about 4-5 years ago...Read More in my yard along the fence line and it has taken off quite well in spite of my two dogs playing tug-o-war with it. But I haven't gotten any blooms on it yet. I'm not sure if there is a dormant stage after planting or the blame lies with the pups. This year it's surrounded by fence and away from the dogs. Will it bloom? We'll have to wait and see.

It has sent out many shoots that many people have been more than willing to take and try to grow themselves, but they have not taken over my yard. The shoots are very hard to start, but those that have succeeded have been more than thrilled with their results. No one in my family, or anyone I know has ever broken out in a rash from this plant. My plant has just started producing seed pods and I'm excited to try this method of propigation of this great plant. I have not had a big problem with the plant taking over with proper trimming. I hope that more people will have a good result with this plant.

Luckily for me, I saw this vine in glorious flower, covering a house and obviously doing damage to it in Riverview. It was scary to look ...Read Moreat. Think of kudzu and walk away...

I am presently covered with a rash from this plant from head to toe--it is quite unpleasant, and I was wearing long sleeves, long pants, ...Read Moresocks and gloves when I acquired this rash--the allergens penetrated through my clothes to my skin. I doubt that there is a square yard on my entire six acres here in NorthCentral Florida, zone 8b, where this very invasive native plant does not grow, so I have to pull it out, roots and all, in order to grow anything else. It makes long roots as thick as my fingers, that intertwine in the top six inches of my sandy soil, and my hands ache from pulling it out of future flower and vegetable beds. It sends out long underground runners, as well as long vines, up to 40 feet tall, or taller.

I have just spent three hours on the internet researching glyphosate, the active ingredient in RoundUp, as I am desperate to get rid of this invasive plant. I have much more of this plant than I have poison ivy, although I am equally allergic to both.

I have also been given some homemade weed killer formulas, one of which I am considering trying: take one gallon white vinegar, one pound of salt, and 8 teaspoons of dish detergent as a surfacant, and spray. It sounds more organic than RoundUp, but I'm worried about the salt residue and damaging my many earthworms and other beneficial insects. Supposedly RoundUp binds to the soil and is transformed by soil microorganisms into carbon dixoide within a few months. As a lifelong organic gardener you must realize how desperate I am to get rid of this plant if I am even considering using something like RoundUp. So if you don't want to be in my predicament, do not plant this plant! And so much for all the ballyhoo about wonderful native plants--I'd certainly much prefer a well-behaved, attractive, cultivated vine that knows how to stay in its place.

I do understand there are some better behaved, named cultivars of this plant, but after battling this plant for a year I don't think I would ever plant any variety of it. The irony of it all is that the pretty, orangy-colored, trumpet shaped flowers of this vine trailing along the front fence and up the old oak trees arching over the white limerocked dirt road attracted me to stop and look at this property in the first place--and it was only then that I saw the "for sale" sign, mostly hidden by these "jungle vines." But my hands and forearms literally look like "raw meat" right now from handling this plant, so if you are at all allergic, do not plant this thing. And from the other comments I think it is very obvious that the further South you live, the more invasive it can become.

The wasps are imposing but haven't harmed anyone. Haven't seen any ants, though. And there's a delicious drop of nectar if you break off a blossom carefully and suck on the base, like honeysuckle. This year for the first time I have seed pods.

So when I decided to move it to another place, I planted it in a 5 gallon black plastic pot. First I cut the bottom of the pot out, dug a hole for the pot to set in about half way up the side, filled with my garden dirt, planted the vine.

It is now contained and I do not have the invasive shoots in any other part of my flower bed. It has been there three seasons now and so far I have not had any extra shoots coming out of the ground as it did in the other spot. I find that any plant that is know to be invasive can be planted in this manner to contain it.
