Ailanthus Species, Chinese Sumac, Ghetto Palm, Stinking Sumac, Tree of Heaven, Varnish Tree

There is research currently underway through Virginia Tech on a control method for this invasive species. You can read a summary here: [...Read MoreHYPERLINK@www.richmond.com]

I'd like to encourage all gardeners to plant native shade trees. Here in NM a cottonwood, or a sycamore, would be a great substitute for...Read More ailanthus, and much more beautiful! The invasive, non-native species that are sucking up the water and crowding out the natives are doing enormous damage to our environment.

Invasive junk tree in my opinion!

You don't want this invasive stink tree! For those of you who are old enough to remember the novel and movie "A Tree Grows in Brooklyn,"...Read More this is the tree that forced its way through the concrete sidewalk. The only interesting thing about this tree is why anyone would call it a "Tree of Heaven."

I'm no accomplished gardener, just a despairing homeowner who happened upon this discussion. This tree is overtaking our entire block her...Read Moree in Nevada, and growth in neighbors' yards is directly obstructing our mountain views - views that prompted us to buy our home just THREE YEARS ago. We're slowly beginning to talk to folks about it, but wow, how awkward. Can you really tell someone to spend the thousands of dollars it'll take to overhaul an entire yard? Of course not. We manage our own property, but without a community effort, it's hopeless.

My advice: never, ever move into a neighborhood with this noxious weed if you care to protect your home values and landscaping. And please realize you're the neighborhood menace if you're propagating it. You have no right to.

One of the worst weed trees ever. Fast-growing, but the wood is dangerously weak and large trees often drop large branches and whole sect...Read Moreions of the crown. (Take a close look at a dozen mature trees and you'll see the scars/stubs.)

The shallow roots damage foundations and heave driveways and sidewalks. They outcompete other nearby ornamentals and inhibit the growth of lawns. They are known to give off toxins that inhibit the growth of many other plants.

Self-sows prolifically both in towns and in native habitat (especially fields and woodland edges and openings), where it forms extensive monocultures.

Males in bloom give off a pungent stink, as does the crushed foliage.

Cut tree trunks and root suckers usually resprout repeatedly unless treated. Painting the green inner bark with 50% glyphosate or triclopyr immediately after cutting (within two minutes) will usually kill the plant.

This species has naturalized in 44 of the lower 48 states, as well as Ontario and BC.

Sale, purchase, transport, and planting this species is illegal in MA, CT, VT, and NH.

In WI, its transport and planting are banned under NR 40.

Invasive "noxious weed" tree. This tree grows all over North America. It reseeds itself easily. It is on properties that are not cared...Read More for. It has a foul pungent odor. The tree has no redeeming qualities. If it is on your property ...... do the world a favor and remove it.

Perhaps Rio Rancho, NM, high desert, little rainfall and sand, is the only place to truly appreciate the Tree of Heaven. With the diffic...Read Moreulty in growing anything here, I love the Tree of Heaven. I have several very large, beautiful shade trees. They grow very fast, are quite pretty, don't get bugs, don't require much water, no pruning and the leaf clean up is easy in the fall. The perfect tree!
A lot of the problems mentioned in all the negative replies do not seem to be applicable to the tree in this local. Yes, there are "babies," however a quick swipe with a loop hoe quickly removes them. If smelled closely, the tree does have a slight peanut buttery smell but I have never noticed a strong or offensive odor. I have native plants growing under my trees, so the poisonous factor doesn't seem to apply here. When removing a larger one, it was no more difficult than any other tree.
I would not plant a Tree of Heaven, or any tree, too close to the house as roots can present problems for the house foundation.

Although the tree is considered an invasive and is capable of taking over areas where established, especially disturbed areas, there are ...Read Morewildlife benefits. Large patches or groves of these trees provide an ideal location to create a cavity nesting sanctuary for birds. I have gone into these groves with my chainsaw in the winter and will double band girdle 10 to 15 of the larger seed producing females. They will die rather fast, (one growing season) and will create snags that are quickly utilized by many cavity nesting birds. I viewed a Wood Duck actually using a natural cavity as a nesting site in an Ailanthus tree this past spring.
The snags created seem to last 5 to 10 years before they decay enough and fall to the ground. I will revisit these groves every 3 to 5 years and girdle another 10 to 15 trees. It is amazing the number of different birds that use the newly created snags.

This tree spreads very fast by seeds that is has become invasive and (in my opinion) even a serious threat to our native flora in Europe. So beware!

as a hopeful future arborist i can honestly say i dont understand the intense level of hatred for these trees.

i will star...Read Moret out by saying that i have been observing these trees for a little while now and have seen many things unexpected. infact the more i have observed, the more interested in this tree i become. i will not deny that this tree is a rapid reproducer and use of this tree should be limited. i want to make note that within the landscape community its perfectly acceptable for hackberry, silver maple, and basswood to spread intensely but not ok at all for tree of heaven just because its not native. i personally find that silly and quite ignorant of how plants behave by design. i have an interest in ALL trees and think they all should have a chance.

i have read about people getting rashes from these trees, needless to say since i have been messing around with them so much i cant say i've ever gotten a rash or any other negative reaction from touching the leaves. howabout the supposed smell it produces. the leaves and broken branches can smell of a peanut butter type of smell ITS NOT FROM THE FLOWERS. i once stuck my nose right into a large male flower and smelled absolutely nothing.

i have seen seedlings come up as a result of a female tree in an area that had not been mowed within the first month or so of spring but as soon as they mowed, i saw only a few survivors which just were mowed over again. i just need to say that ALL plants require maintenance even if all you have is grass.

everyone is entitled to their own opinion but i just dont see a real reason for so much hate other than irrational overexagerated information.

More like Tree of Hell. This tree stinks. Literally and figuratively. It crowds out other species of trees more beneficial to wildlife and humans.

This "Tree of Heaven" is also known as a "Junk" tree because it is found in old rail yards, neglected properties and around warehouses.Th...Read Moreis "tree" was sent to our neighbor as a sapling from Colorado by his brother sometime in the 70s. My husbands' family lived here at that time. It grew very quickly and after it grew to about 20 feet it began sending out seeds and runners that went under the concrete wall in several places and created new trees on our side and in neighboring yards. It killed the Cherry Tree and raspberry bushes my in laws had planted in the 60s and cultivated every year. They cut down each stink tree as it grew in this yard but it would always regrow. After we bought this house in 2000 we spent every year digging out as much of the roots and the trees on our side and then the baby trees that grew from seeds. They grew everywhere; in cracks, next to the house, inside other bushes etc. There were over 1000 every year. They were in neighboring yards and other neighbors, as well as us, implored the homeowner to get rid of the tree but he would not. Upon his passing, his family hired a tree company to come out and poison and remove the tree. At that time the trunk was 3 feet in diameter and about 80 feet tall. The company used Garlon 4 to kill the tap root and many of the runners. After the tree was dug out and the remaining trunk and runners ground down it took 5 good years of constant digging in his yard as well as neighboring yards to almost end the growth. Unfortunately, new trees have popped up in the neighborhood and are about 15' at this time. One neighbor cuts them down every year. Another has given up and others don't know. I have just enough poison to protect my yard and a few of my neighbors yards but there are just too many all over now to handle alone. I will never buy a home with a stink tree in the yard or anywhere in the neighboring yards. Many of my neighbors feel the same.

Three years ago we purchased a home in Magalia, CA. On the side was a beautiful tree. Lush with shade. It was about 30 feet tall. Around ...Read MoreJune, we started smelling something that was very pungent and unpleasant. We at first though it was out neighbor who worked with epoxies. After a few days when the flowers were in full bloom, we realized it was that tree that stinks. Nobody knew what it was, and I had a devil of a time finding an identification for it online. Finally I thought I would put in the search engine. "Invasive tree that stinks", and that did the trick.

Three years later, the tree is about 65 feet tall.

Personally, I like the tree. But I am constantly pulling it's babies out of the ground all over the yard. I usually wait until they are about a foot tall because then it is very easy to get the full root. If they are too small, sometimes the root breaks off, and then you just have to pull it again later when it grows back. It really only takes a few days for the thing to become a foot tall.

I have purposely left two of the young ones growing, for the purpose of experimental pruning. One was 9 feet tall after one year, and I cut it off at 3 1/2 foot and stripped all the side branches off. It grew a new top within 2 weeks, and is now a controllable and very nice tree, at about 8 feet.

The other one, I did the same thing, but only let it get to be about 3 feet tall, and I keep the top cut off. It grows wider and is now quite a lovely bush.

The experiments were for the purpose of seeing what would happen if we were to cut off about 40 feet of the big tree, which we will do as soon as it drops it's eaves this fall. We love the tree, but it is out of control, and we really don't want it to break off and hit the house.

You can enjoy these trees if you have the time to trim them about every 3 months. (and I you can stand 2 weeks of stink)

By the way, the more we pull out, the fewer we see sprouting up. The first year I must have pulled 100. We are down to about 20 this year.

I have not had the issue of these things growing from "seed" as some of you mention. I believe mine is a male tree. Some horticulture sites say only the male tree stinks....well, then... who's making all the babies in the yard. I think mine are actually coming from runners. The tap root always takes a sharp 90 degree turn from the stalk just below the surface, and at the bend, there always appears to be a raw spot on the root, as if it was broken off, but the taproot is whole. That's why I think they come from runners.

I work in an industrial area and we have this tree growing in our parking lot. It was originally growing all over one of our side yards, ...Read Morebut we managed to eradicate them. We pulled them all, rototilled, spread anti-weed fabric, and covered it all with three inches of pea gravel. Not another one since. We do have several sprouting out of a crack out back, in between asphalt and the concrete warehouse next door, one literally grew out of a seam in the wall, about a foot up. I've tried cutting them down but they re-sprout as I can't get to the roots. None of them seed or flower, so assuming male plants. They smell funny. I've given up trying to eradicate the remaining plants and just prune them each year so that they don't go haywire back there, the added shade is a nice touch. Was considering planting them to help as a windbreak at our ranch out east, but after reading all the comments about it I think a different species is a good idea...

Most annoying and invasive tree ever. It can grow really quick and I always pull them out wherever I see them, no matter where it is.

This is the ultimate weed tree. It should be called Sumac-leaved Stink-Tree, as it smells terrible. It is very fast growing with brittle,...Read More soft, wet wood and it is very messy. It often ground suckers from the roots and forms a colony. It escaped cultivation long ago when some guy brought it back from China to Philadelphia PA thinking it would be food for silkworms, and Chinese immigrants brought it to California. It does not blend well with the native forest, and is an invasive pest, pushing out better plants. I actually don't mind some in the most polluted and dirty spots in the big cities, although it comes up in any big crack in paved areas. It is very tropical looking, like all its many tropical relatives, and can be used in a tropical style landscape; hopefully a male plant that can't make babies.

This tree has damaged our foundation here in Ohio and attacked our porch. We have a tree in the front yard it was around, and thought we ...Read Morehad gotten it out but now there are limbs shooting straight up from the normal limbs of the tree.

Has anybody ever seen this stupid tree parasite another? It's the creepiest thing I have ever seen.

Fortunately, buying and selling this plant in my state is illegal due to the havoc it's created in the ecosystem. Unfortunately, its alr...Read Moreeady so prolific that it's taken over large areas and killed off many native species. (The horrible rotting-peanut smell is an herbicide it produces to inhibit competition) But for such an aggressive, rugged species, it's an extremely short-lived tree, living roughly 20 years on average and rarely over 50 years. It compensates though seeds that almost always root and suckers under the ground. Seedlings are fairly simple to eradicate, but the suckers are much more difficult. The NPS and USDA sites have a good list of recommended ways to manage this problematic plant.

Incidentally, the low-growing shrubs which feature the beautiful red plumes are our native Staghorn Sumac (Rhus typhina) which does not have serrated leaves and acts as an ample food source for native wildlife.

I am glad to finally know what the mysterious plant growing outside my kitchen window is. I wouldn't mind the tree if it wasn't growing ...Read Morein my basement window well! I have been debating planting flowering shrubs on either side of the window well but have been hesitant because this thing keeps growing to a ridiculous size. Unfortunately I rent, so I am limited on what I am allowed to do to remove it. The landscaping and/or lawn crew here really don't know what they're doing and have trimmed this tree back once, which of course it grew much bigger afterwards. This summer I trimmed it myself since our ex-neighbors left trash laying around and it had blown into the window well under the tree (or they stuffed it there so they didn't have to deal wth it, either could be true). I didn't care for the tree before, but after the smell I really want it gone. It was here before we moved in, so it was already well established, just cut back every so often I guess. At least now I know what I'm dealing with and can attempt a removal, or try to kill it. I can't imagine what kind of damage it may do in the future to the window well. If only it wouldn't get so huge - I do like seeing a living plant right outside my basement window.

There may be a way to control this plant, but before I mention that, consider 3 problems. First, cut the darned thing down (leave about 4...Read More' of "trunk" but no foliage--see below) before it makes seeds. 2nd, be prepared to pull seedlings growing from old seeds already in the ground. 3rd, it will spread by lateral budding from the roots.

Now for control. This "tree" seems to have very shallow roots, that is, no tap roots. The entire root system (all of the trees may be connected to one another) may be limited to a depth of less than 2'. You can dig down about a foot to the main roots, loosen them, and pull the "trees" out of the ground. Cutting the "trees' off at about 4' and removing all foliage a while before doing this weakens the roots and gives some leverage with which to wiggle the root system out.

Control otherwise requires constant removal of even the tiniest amount of foliage, which starves the root systems and prevents spreading.

When my husband and I first bought our home I thought "oh wow what beautiful trees we have growing in our new yard". WRONG! There was a s...Read Moremall bundle of about 5 of these trees decorating the front yard. I thought they were pretty, but my husband thought they might be sumac. Well I swayed him from taking them down which we really haven't had the time anyway, and now they're everywhere! I'm pulling up these tiny trees constantly! I wouldn't mind if there weren't like 500 seedlings popping up weekly. I would like to have a yard for my son to play in! Unfortunately we haven't been getting much rain and if we mow our lawn again it's probably going to die because it does not need to be mowed. However that is my quickest solution for ridding the seedlings popping up everywere. I don't have time to be pulling these things up all day since we have a 2 acre yard! I would like to find a solution that does not involve harsh chemicals because we have a 7 month old who loves to play outside. If I could sadly find a way to kill these beautiful monsters, in a way that will not jeopardize my sons well being, I would have done so already. After that task is complete, I will be on the hunt for something that is similarly beautiful that will flourish in my area but not over take my yard.

I also have a new name also for it Black sumac, siemier behaver as the Black walnut tree if you think about it. That does the same thing puts out thing in the Growed that other trees can't grow around it also. just a thought about a new name for it.

my wife and I bought a new house one year ago, and we had two of these "trees" growing outside of our backyard fence. After finding out ...Read Morein January what they were, we had them professionally removed in February, including having the stumps grinded out. Frankly, we haven't had nearly the problems (yet) that most of you mention. The first month or two of spring I had to go around the yard every day or two and remove the tiny sprouts, which I assume were from last fall's seeds, not existing roots. This summer, I've found, maybe, a dozen or so suckers popping up in our yard, treated them with RoundUp, and then pulled a day later. I haven't noticed any suckers popping up around the former site of the tree.

I have been fighting this tree/weed for over a decade. when first sprouting it looks like a pecan tree but beware. It does not need even ...Read Moreneed sun. I have one growing in between my porch post and molding. no soil there, no water no sun. You may stunt them but don't be fooled they will return. I lived in the same home for 10 years. Neighbors had a back yard full of these. The seeds always found there way into my lawn. I managed to keep them under control with regular weed prevention and catching them early. Now I am in a new home with two large ones that have grown into and destroyed the fence between properties. Literaly hundreds more that must be managed at minimum weekly. I was performing my regular trimmings last Sunday and cutting the limbs from the fence from the tree in my neighbors yard. I always itch when they touch my skin and the smell is noxious. I noticed red itchy bumps starting but kept cutting. I started feeling a tightness in my chest and difficulty breathing. I was determined to keep going to they didn't destroy the fence. I finally finished the trimming and put them in the trash cans. I got them to the gate and began to feel lighted headed. I left them there and ran inside. I washed my skin and took allergy medication. By this time my throat was swelling shut. I saw my allergy specialist today who said my allergy was related to fungus. I live in the Chihuahuan desert. Fungus? does any one know if this weed has fungal properites? I do not recommend this tree. You may like it but it will take over the entire neighborhood. Not very nice for your neighbors who don't want to deal with them. May be pretty and provide a forrest like atmosphere but will destroy your yard and house.

Now it's just an ugly stump but there's more of them trying to overtake the back yard. And oh the horror of their smell when you take off their leaves, ahhh. Apparently some people like the smell, but my family and i really really dislike it. I do not recommend this plant and hope everyone who has it and dislikes it can get rid of it easily.

It wasn't until this year it finally died, I have no idea why. I absolutely hate these with a passion, and they grow everywhere here.

Honestly, I love these trees. I love cutting down the little shoots that pop up all the time. The reason they call this "The Tree of H...Read Moreeaven" is because you get to play god with it. Nothing gives me greater satisfaction then taking my lawn mower and mowing down the miniature forest. My favorite thing to do is look up through the canopy when the wind is blowing, because it makes me feel like I'm in the jungle. The green leaf pattern backed with a blue sky is amazing. Utah is not a tropical climate and so this tree is as close as it gets for us elevation highlanders. Another thing I love about them is how after they lose their leaves, and a strong wind blows, all of their season growth branches come down. It's fun ranking them up and throwing them in the garbage. If you want a great privacy fence, plant these trees and you'll have a great grove in a couple years. I give the Ailanthus altissima five stars and two thumbs up! If you want to control them, don't cut them down and when the females put out their seeds, just harvest them. I collected a five-gallon bucket last year of those seeds, and am about to plant 72 of them for the new house I'm moving to this month. If you don't want them proliferating, just harvest the seeds with a ladder or hydraulic lift, and then burn the seeds. If you have neighbors you like, I highly recommend this practice.

Like for most of us, there are always invasives where we live. I know mine will die from weather so I let them "be" there and I enjoy them in their short life-span in the mountains. A year ago, grasshoppers feasted on them! We had a different moisture pattern this year so I didn't have any grasshoppers.

Perhaps Japanese knotweed would be a suitable rival for the first prize. It grows everywhere where it shouldn't and is extremely hard to exterminate. Until last summer, I had 10 individuals (!) of this species in my garden, who fortunately could not cope with the drought and didn't grow as vigorously as they do elsewhere. After many years of angry controversies with my father over this piece of horrendous junk, I cut them down with an axe, my father's lamentations notwithstanding (he thought they were BEAUTIFUL!!!). He leveled them by cutting the stumps to the ground with a chain-saw, yet I am sure there will be a lot of work to be done with the help of total pesticides. In addition to the now deceased grove of trees of heaven, the neighbour's yard harbours a large and sexually productive individual that keeps dropping seeds that germinate right beside precious plants like palms. Pulling the thing is of no use, because they regrow, and cutting and digging does not come into consideration. This is a gardener's nightmare.
Oct. 2009 Update - after cutting to the ground, this pariah of the tree world has been sending suckers all over a large perimeter on our plot, obviously from its roots.

This tree is smelly, invasive, poisonous to other plants and almost impossible to destroy. The only positive attribute it has (its beauty during the winter) is not enough to overcome its negative aspects. If you see it in your garden, kill it. With fire.

The positive attributes he m...Read Moreentioned are true of most trees so it doesn't do much to warm my heart to his plant. Don't misunderstand, I think it is impressive, attractive, and just fine in its native habitat. But it takes over once diverse areas of forest and diminishes diversity by outcompeting many species and having no food value for most native animals. It is not a "control issue" any more than reducing polutants which we have wrecklessly unleashed into the environment.

Possibly the only thing worse than Ailanthus would be a patch of Kudzu growing up and around it!

Maybe instead of crying about how this plant ruined your life and saying how horrible it is, lets try to see the good too.... explore its use as paper, bio-fuel, erosion control, or neighbor screening and repellant.

Think about this.....If you are concerned about a plant taking over, you are upset because of a control issue!You are upset that you can't control a species just as determined to survive on this earth as you are.

This thing is evil. I can't kill it without digging up my neighbour's yard, which I'd gladly do if he'd let me. Thats right. I would personally go and dig up that stupid root if it took all afternoon, and I'd even buy HIM dinner aterward.

I am constantly pulling sprouts in my yard. I'm afraid it got it's start here in VA back in the late 1700's and it has spread like wildfire all over this country, taking over habitats and replacing native trees. Like Kudzu and Japanese honeysuckle, there is going to have to be a concerted effort by many to remove this tree, if we ever can. Why anyone would actually sell or buy this tree is beyond me.

It looks like there are small trees wrapping around a big tree beneath the bark, but there's not, that's just the twisty shape of the way the wood grows. Grows fast, tall, big and full.

Otherwise, I don't like this tree at all. For the longest time, I could recognize the scent of this tree, without knowing what it was. My friends and I would gather firewood from the woods when camping. Sometimes I could smell something in the fire burning that just stunk. I always thought it was weeds, but now that one of the trees are in my yard, I know.

There's nothing like it, and I can honestly say that this is the WORST scented tree/plant I've ever smelled. Rotten tomatoes smell better to me than this tree does. The smell doesn't make me fully ill, but it will churn my stomach after a few minutes. The other day I picked up a branch that fell off the tree and had to go wash up a few times because of the lingering smell.

Invasive is an understatement for this tree. Starts out looking like a small weed with a lot of leaves and quickly grows. Survives drought well.

Extremely negative, that is.

There are about 7 phases of stuff that fall from these demon weeds. Not to mention what drops from the pigeons who hang out in them. But that's a whole nother story.

I just found out that Ailanthus trees emit toxins which prevent other plants from growing. Wish I knew that about 5 years ago. What I couldn't find out is where the toxins emit from. Roots, leaves or the various other things that drop from them. I suspect it is in the droppings because even potted plants in my yard battle to survive.

One funny story to illustrate how aggressive this demon weed is: I was renovating my apartment which is about 5ft below grade level. I removed the old floor right down to the cement foundation. I laid down some plastic as a vapor barrier then built a wood frame and covered that with plywood. I took up one of the plywood boards once and saw what looked like a yellow extension cord under the plastic. I cut through the plastic and realized it was a root from the tree. It had grown 30 feet underground and under a slate patio, found its way through the concrete floor and spread out under the plastic for about 10 feet inside my apartment. All in less that 6 months.

I strongly recommend that you do not plant these and yank them as soon as you see them growing. They are taking over along the highways in NY and NJ. It seems like there ought to be a federal level plan for dealing with them.

I tried to find out what they were then, thinking them resembled some type of Sumac. But I couldn't place those chartreuse samara clusters. I later confirmed they species to be an Ailanthus, but now that I know what it's popular name is I dislike it even more. Choosing to be wary of anything of Chinese or Eurasian origin on the outset is my first response, and Ailanthus altissima, as with most other plants from that region, has stayed true to form by over adapting to our Western climbs and proliferated into a nuisance at the risk of loosing native fauna. I can't believe they sell it in some places, or that anyone in this day and age would care to cultivate it on purpose. It threatens our native habitats, forests, fine marshes, fens and meadows and that in and of itself is reason enough for systematic eradication from our landscapes. It's about time we reverse the trend of our less informed colonial botanists and horticulturalists. The Selling or growing of anything exotic with the potential to get out of control should be banned.

If you have read this far you will have come to the overwhelming conclusion that this tree is a spawn of Satan himself. It grows where it wants and is extremely hard to kill.

My family has had to remove these trees for years but the best personal story is a tree that was growing INSIDE our shed behind a pile of boxes, from a crack (it created) in the base board and the wall. There is NO light and the tree was struggling but still growing!!! (very white in color and about 1.5 feet tall)

Most of this was grubbed out and there are stubs all over. There is even an older one (3" in dia.) growing around a water pipe. I have a long battle ahead of me.

Nevertheless, the trees give the lanscape the tropical view, add to the air the peculiar scent and make local cows' milk spicy.

The older parts of the east side of town had (still have, no doubt, thirty years and more after my childhood experiences) huge specimens, eighty feet or taller, and any alleyway in downtown or an industrial district with a bit of sunlight would magically spawn at least one. No neighborhood seemed immune: the older, poorer neighborhoods with the giant trees had more, but any yard -- even the middle of a ten-acre tree nursery in the north of town -- could have some show up as if by spontaneous generation. Grubbing out the roots was generally indicated when they did.

The most impressive infestation I have seen was in Boulder, Colorado when I lived there in the early Nineties. In one old hilly neighborhood where I'd sometimes go walking, there were a few large trees, apparently cherished, in the middle of well-tended lawns, and down the block whole hillsides taken over by roots and suckers.

(Silkworms: apparently there is a moth with a larva called the ailanthus silkworm, but it is not the usual silkworm of commerce, which eats mulberry [or in a pinch the related cudrania's] leaves. I don't know whether this insect's cocoons are harvested for silk; various moths have been used as sources of silk in the past and even nowadays, so I guess it's possible. Chinese miners introduced the ailanthus to California's gold country, but whether they were trying to start a silk industry I have no idea.)

Look people, here's the reality of life in major urban centers: there's way too much pollution, way too much dog urine, way too much road salt, for any other tree to grow in 80 per cent of the city.

In the 50's and 60's, urban areas were filled with large shade trees, such as those famous lamented elms. They all died. Now, cities only enjoy 16 per cent of the trees they once had, thanks to pollution and salt.

No other tree that's regularly planted, not even those honey locusts from arid Texas, can take that environment.

You complain that the tree "smells". How 'bout car exhaust, doesn't THAT smell? How 'bout chemical effusions, doesn't THAT smell? Yet, no one seems to be keen on eliminating cars and chemical factories. Yet this brave little tree, that can grow ANYWHERE and actually help with reducing pollution (yes, it's true, the tree metabolizes and neutralizes the effects of sulphurous pollutants in its tissues, we're still trying to figure out how).

Another thing, nothing eats them. How many times have I seen and heard about yet another bug from yet another continent decimating yet another variety of tree? This one's impervious.

It grows fast, it spreads well, it makes shade. What more do you want from an urban tree?

Yes, I would not plant this one in a forest, but most people I know don't live in forests. Nor do they live in a suburb--again, another place I wouldn't plant this. But they DO live in cities, and I think EVERYONE who lives in the inner city should be GIVEN one of these to plant.

Heat islands made by cities are terrible environmental problems, this would solve them. It'll help with air pollution too.

As for what good is this tree: its extracts have many medicinal qualities, its leaves make silkworms produce stronger silk, its wood (when treated properly) is hard and useful.

I have them growing everywhere, but they are smallish, and weeklike, not full grown trees. I had planned on letting them grow out, as I think they look awesome.

Although this tree is considered a Noxious Weed in PA, from my own observations, I can say this: I have only seen it growing in recently ...Read Morecleared areas or fields that haven't been cut in a while, and at the edges of woods. I have also seen it growing around abandoned limestone quarries, where almost nothing else will grow.

That said, I have also noticed this: around the rock quarries, as the fallen leaves and branches of this tree add some kind of soil to the bare rock, native Eastern Red Cedars have been moving in and are pushing out the Ailanthus trees, and in fields that have been left to go to forest, native hardwoods eventually move in and shade out the Ailanthus trees. These trees (from what I've seen) are completely intolerant of shade, on top of which, they also are among the LAST trees to get their leaves in the spring (Black walnuts are a close contender for that title, though), and among the FIRST to lose them during the fall, putting them at a further disadvantage in competing with native trees for sunlight.

Therefore, I'd class this tree as an aggressive pioneer species (in terms of forest succession), especially for unforgiving locations like abandoned rock quarries or strip-mines, that is eventually supplanted by trees that are further along the succession scale (i.e. Mullberries, Red Cedars and Boxelders move in next, followed by hardwoods such as Oaks and Maples). I'd only recommend to let it colonize places where other plants won't grow, such as abandoned strip mines or rock quarries in order for them to convert the mine-waste/bare rock into soil that other plants can use. Otherwise, don't touch it with a ten foot pole.

Oh, and one interesting fact: this tree is the primary food of the silkworm caterpillers in China, and is why they called it the tree of Heaven. The tree was introduced into the US in an attempt to start a silk industry here, but, due to America's high wage scale, the industry collapsed, and the trees and silkworms escaped into the wild. Fortunately, the silkworms ONLY eat Ailanthus, so they did not become another gypsy moth type fiasco.

I thought that if I put a barrier two feet down into the ground it might give me time to kill what suckers I have and to get a good stand of a shrub that is thick. I thought the shaded area would be less hospitable for these trees. That is, until today, when I saw the eight foot tree coming through my dogwoods.

It forms virtually solid, standing thickets like ...Read Morebamboo, crowding out native plants, by propagation and huge seed production! The seedlings and young trees are about the most invasive plant I've ever seen!

It can grow anywhere: healthy native upland hardwood forests (both adult and young trees), along streams, rivers, and creeks, along roadsides, fences, in vacant, weedy lots (especially!), in open areas, in small corners of space around homes or buildings outside, EVEN IN CONCRETE CRACKS AND IN CRACKS IN BUILDING WALLS! Around old buildings, it can grow even on rooftops made of concrete and in the smallest spaces available! IT SEEMS LIKE IT DOSN'T EVEN NEED SOIL TO PROPAGATE AND GROW, IT CAN EVEN CRACK AND GROW THROUGH CONCRETE!

It even tolerates air pollution, helping it compete successfully in cities and towns. I've seen it especially invasive in the northeast U.S. when I visited southern Connecticut! It seemed like almost every time on the side of the road I saw this tree, whether it was in invasive stands or an adult tree alone by the woods or somewhere! This tree is now present in much of the Eastern and parts of the Central and East-central U.S. and was also introduced on the west coast (in the 1800s from its native China to the U.S. as a LANDSCAPE TREE!).

If you see this plant in a nursery somewhere, please don't buy it! It is WAY too invasive in the landscape unless you are on guard every day and torture it to keep it under control, even though it looks tropical! Also, if you have this tree, get rid of it by cutting it down (the entire tree including the roots - if you leave the roots in the soil it may grow back) as SOON AS POSSIBLE!

MORE FACTS - Very fast-growing; can survive freezes in northern states or states with snow in winter. Releases huge numbers of invasive seeds as well as propagates by root. Native plants are MUCH, MUCH better by far for the landscape as an alternative!

HATE THESE THINGS!!!

HATE 'EM! HATE 'EM! HATE 'EM! (or did I say?)

I echo every negative sentiment here and...Read More will definitely resort to CHEMICALS to TRY to get rid of it ! I've already taken to paying my seven year old a quarter for each berry she collects from the ground and gets put into the trash!

I cannot think of ONE redeeming factor for this wicked thing that is a sorry excuse for a tree!

An awful, awful plant that destroys native forests and can destroy your landscape, if left unchecked. One of the most invasive species on...Read More earth, only good in China, terribly stinking. Grows back easily by suckers, spreads like a weedy thing by seeds. Don't plant this plant and, as a matter of fact, kill it if you get the chance. There are tree of heaven pulling parties sponsored by naturalists where people go through woods pulling trees of heaven.

If you want to see more of this plant, I can send you picture of the one that poked through a wall in the bathroom I was redoing. Luckily no one was using it, but scary. Yes, this is a scary plant. It should be called kudzu tree. Yes, this tree could grow through the sidewalk like a tree grows in brooklyn but that's what makes it scary.

I can't understand why anyone brought it here...I think maybe as forage for silkworms...bad idea. It's so sad to see native forest swathed in these things...a real problem in this area, as in many. My perennial bed constantly has these suckers popping up. The saps irritates and stings when you try to pull it up, so use gloves.

Cut down any grown trees you can and inject herbicide into the root....... If you want a fast growing tree or something with a tropical or pinnately leafy look, plant mimosa. Negative times 100...... if I can do that........ :)

I grew up with that tree all around us in Ohio. I now live in North Charleston SC. Guess what! Darn thing followed me! Yep, it's in my ...Read Moreside yard! BUT, I keep it under control. Every once in awhile, I have the pleasure of yanking it out of my flowerbeds! To me, it's as bad as the Pop Corn tree which I ended up with, thanks to a little bird. Due to the new laws, I can't cut it down! Which means, do NOT let that bad boy get started good!

I was laughing at the descriptions about the Sumac trees and called my Mother. She was telling me that in the old days the seeds were used to make a cough syrup! They even made pies with it. I would not recommend it. I heard they were poisonous! One thing, though, you do have to admit about the sumac is the leaves are beautiful red in the fall and the red plume is, too. Now, if it wasn't such a royal pain!

I have never noticed quite how invasive this tree is until I went for a car ride one day and observed it growing in 9 out of 10 of all th...Read Moree ditches, unmowed lawns, sides of the roads, edge of the woods and in fields.

I have a couple of these trees in my backyard at the wood line but for some reason, there is only three trees and it stays only three trees. If I see any volunteers, I will definitely not hesitate to pull them up, though. Removing the mature trees would be quite expensive.

The seeds are easily spread by wildlife, birds in particular, and I have found one seedling in the front yard. I have not noticed the trees giving off an offensive odor except for an odor reminiscent of peanut butter if I get close enough to whiff the leaves.

Edited to say that I don't actually know now, that the trees in my backyard are stink trees or black walnut. Maybe a mix of both? But the rest of my comment is the same.

Here in the South, it's horrible. Seedlings and suckers abound and it chokes out native plants with gleeful satisfaction.

Rampant here in SC. Supposedly this is the tree referred to in the book, "A Tree Grows In Brooklyn". I wish it had stayed up there.

Don't do it! My husband and I bought a house where the previous owner did nothing to his yard for 5 years and we bought it not knowing it...Read More was full of these monsters. "Clear it out" we said... Ha! We clear, pull, clear again and pull again and again. Two years later we are still trying to eradicate these evil trees. We have finally decided to chop them all down and poison the root system. I never use toxins but am willing to make an exception if it will get rid of this tree. I dream of harmless fruit trees. If you are seriously thinking of planting one of these beasts please reconsider. I even have one growing up through the cement floor in my garage!

It cannot be stated strongly enough that Ailanthus altissima is a very invasive tree under the right conditions and is a major threat to ...Read Morenative forests in some regions. The worst I have seen is in central Tennessee, on rich, moist humusy soils over limestone, where Ailanthus is very common even in the interior of mature forests in natural areas. When a large canopy gap is formed by the death of a mature tree, Ailanthus can seed in to the gap and impede reproduction of native species ...as well as spreading by suckers to form dense thickets. I would hope that those in rural areas surrounded by native forests would eradicate this tree from their property if possible.

I have one huge one in my yard, and several million babies. Drought doesn't bother it, since we've been in drought for several years. The seeds are sprouting in the garden where everything else burned up, soil temperature 127 degrees on the thermometer. Cold and snow don't bother it either, I am zone 5, altitude 7000 ft.

In my opinion, the Tree of Heaven is actually a pretty nice tree to have. I can not understand why people would say that the blossoms sm...Read Moreelled terrible because they really dont seem to smell that bad. In fact, I actually smelled the blossoms before, and to me, the blossoms actually smell like butter.

Also, it even appears that the Tree of Heaven seems to be slightly stronger and more flexible than the Silver Maple. On July 5th, 2003, there was a microburst where I live, and from the way my backyard Tree of Heaven was blowing around, that wind had to be in excess of 65 or 70 miles per hour, and no more than 1 or 2 small twigs were broken.

That same wind downed numerous limbs elsewhere, including a monsterous, nearly 50 foot limb from a Silver Maple that actually crushed a car! When I told an old friend about how my tree survived, he said; "The Tree of Heaven will survive almost anything." Also, I was even told that the Tree of Heaven might even be resistant to the Asian Longhorned Beetle!

One positive, since these trees are so high, I've been able to hang some of my shortwave antennas in the branches by using a rock and a line and with a little umph..I can get that antenna way up in there. But the only draw back is that these trees grow so fast in a year, I have to remove all my antennas before they are destroyed.

I also found out..rats won't eat ailanthis. We also had a black locust tree (6ft. circum. trunk) and the rats completely stripped that tree's bark in the branches, so much so that it died back considerably and had to be removed. But those lousy rodents never once touched the ailanthus. Our biggest ailanthis has a 4-5 ft. circum. trunk. I have to give the plant credit...it never gives up. But I'm always finding a way to kill them.

And I have found a way to (so far) successfully eradicate the new growth. I've been using Ortho "brush-be-gone" on it. You cut the plant off at the base and IMMEDIATELY brush the solution directly onto the cut with a paintbrush. I really give it a good soaking, and so far, none of the plants have come back in the treated areas. Keeping my fingers crossed.....

It's a living thing, however nasty it can seem, please don't hate it. Just do what you need to do.

The odor reminds me of skunk. I believe this is "The Tree that Grows in Brooklyn." I can find no redeeming graces for this tree.

I live in the Pacific Northwest area (U.S.), and I have just agreed to pay $500+ to have an 80' tall Ailanthus altisima removed. ...Read MoreUntil the tree removal specialist came out to give the estimate, I did not know what it was; I just called it "that nasty, smelly tree."

Luckily, it is in a part of my yard where it does not drop leaves or sprout other plants, so other than the putrid smell in the otherwise lovely early summer evenings, and the heavy shade it makes, it doesn't bother me. I am going to leave the large ivy-covered stump to provide habitat, although the stump will be poisoned to prevent resprouting.

Do not plant this tree - it will ruin your summer evenings because of the stink.

These trees make excellent shade, and are a truly aggressive species. So, if you have a brown thumb or a dead yard, this tree will boost ...Read Moreyour confidence. You'll have a forest before you can say, "oh-oh."

A previous owner of our property left us several of these trees. It would seem that every single seed they produce (bazillions) will germinate. (We have sandy soil, alkaline with not the best nutrients; temps range from 10-110 deg F; 3,600 ft elevation.) I would estimate that my wife and I kill well over 1,000 sprouting trees, throughout Spring and Summer.

When you pull up these sprouting monstrosities, they break easily, and the tuberous root system re-sprouts multiple trunks. If you keep breaking them off or cutting them down (instead of digging them up) in hopes of killing them, you'll have a crown sending up several young trunks within the same season. You MUST dig them up, or you're stuck with them.

One could almost say that to prompt them to grow, try to kill them.

They are a profoundly messy tree (leaves and the twigs they grow on) and pernicious weed. The wood's good for nothing. I found a way to get these monstrosities not to produce seeds. Prune them. I cut off probably 12-15 percent of upper growth of two of the trees last year at about this time (Jan), and they produced NOT ONE SEED, while the other trees, which I didn't prune, produced as usual. This doesn't mean that the tuber roots won't retaliate this year. We shall see. But at least no seed from those trees.

I don't know why they call this the "Tree of Heaven". Although it is very beautiful and tropical-looking, it has its drawbacks. The tree ...Read Moreis very invasive. It grows any place. Even in the crack of a driveway. The tree grows new sprouts from the root system and or seeds that fall all season. My lawn is half grass half tree sprouts. This tree is the last to get leaves in the spring and when all other leave have fallen this tree still has them, so you end up rakeing in the snow. After the leaves fall then the sticks the leaves are on fall, makes a mess in yard. When you cut the grass the smell is nasty. Even if you have the tree cut down, its very, very hard to kill the root system. Seems it lives forever. Too bad for me... I have one in the front yard and one in the back a million in my grass and some in the cracks of sidewalk and drive way. This tree is way way out of control.

The female tree has a nice display of flowers and seed clusters I find of interest for their longevity and color.
The often described foul odor is, to me, somewhat like burnt peanuts.

After allowing a volunteer to grow in place of my former small pines, unearthed by an unusally wet winter and heavy snow laden branches, I am please that after 5 years it has attained a height of at least 20 feet! It has not, however, produced a single blossom, and I have yet to find a source of information as to the maturation to flowering. Oh yes.. hope it is a Female!

All parts of the tree,especially the flowers,have a strong, offensive odor. This is a prolific seed producer, grows rapidly, and can overrun native vegetation. Once established, it can quickly take over and form a thicket. The root system is aggressive enough to cause damage to sewers and foundations. Should be considered a weed as once it gets started its impossible to get rid of.

Since I really can't see anything good about this tree wonder how it got the name Tree of Heaven...
