Aegopodium, Bishop's Weed, Goutweed, Ground Elder, Variegated Snow on the Mountain 'Variegatum'

Bought a 1940’s house in 2018 and these suckers are coming into our yard from under the deck and through both neighbors’ fences. Itâ€...Read More™s impossible to get rid of and has strangled more than one clematis.
I have to admit, the variegated foliage is attractive, but please for the love of god, do not plant this

This plant should be banned from sale in North America. It is destroying native habitats by the acre by destroying all native plants in i...Read Morets path. I am fighting a sprawling acre of this monstrosity at a property I purchased a year ago. The previous owner had been fighting it for years and thought he had eradicated it but this year it showed up in full force. The beds had many different rare and beautiful native plants, but is being steamrolled into large swaths of this one plant.

It does revert to its non-variegated form, it does set viable seed, it can have roots a couple yards deep. No, you can’t keep it under control. Please, no excuses, stop growing this plant.

Honestly I sometimes wonder why some people garden. Plants don't seem to me to be cause to get all that emotional.

As vari...Read Moreegated plants go, this is one of the most attractive and bomb proof choices that you can find. Despite some claims, I have never seen this revert in over 45 years of gardening, not once. I don't think that I can say that about any other variegate out there.

Would you buy a Great Dane puppy if you lived in a studio apartment, and then blame the dog when it grew too big, because you didn't do your homework? Would you buy a compact car and then wonder why you couldn't use it to tow a fifth wheel trailer? Gardening too takes a little knowledge and research to be successful. Mistakes, failures and unexpected results are not the fault of the plant.

Historically this is a plant that has been used at summer cottages, among other things. In my area there are many summer homes which have had it in place for decades, generations even. It's hardiness and few requirements meant that it could easily survive long periods of neglect while cottage owners were not in residence for much of the year. The last thing that they wanted to do when at their summer house was to worry about doing much landscaping care. They really understood what it was to get away and enjoy the country and nature, yet gardening types still wanted a few ornamentals around.

I keep it at my cottage for both it's beauty and to honor it's historical use. I even keep the non-variegated type around just to have it, and yes to annoy the more uptight people. They both can be real conversation starters, and when other gardeners visit, their reactions to it helps me to weed out the sensible folks who are more deserving and able to engage in meaningful gardening talk from the hysterical lunatics who can't see beyond their own ignorance.


With just a little bit of research it is easy to find ways to site this so that it doesn't spread. I know, to some people all chemicals are horrible cancer causing boogy men which are going to destroy entire families and neighborhoods after even one or two applications, but for those who can read and follow instructions there are ways to get rid of it that aren't going to kill every bee for miles around or cause every child in the neighborhood to be born with birth defects. Yes, really.

I thought I'd cleared it out from a shady bed last year, but it came back this year as though I hadn't ever touched it. It's too successful

I live in MA and this plant has taken over countless acres of land. I live on 2 acres and the plant goes on for miles and miles in my ne...Read Moreighborhood. It has destroyed any indigenous plants I may have once had in my woods and will absolutely take over anything In It's wake. Please do not plant or propagate this horrible ground cover.

The good news is that I have been in my home for 4 years now and I have been able to mostly eradicate it from parts of my yard but it takes years to do and it's near impossible when the whole town is overrun with the stuff.

Round up was only a temporary fix especially if it's been reseeding itself for years before you attack it. You'll kill the plant but the seeds in the ground will sprout right back unless you heavily mulch the area.
I have only been successsul when I started a new bed from scratch. I gingerly pulled weeds with a pitchfork for 2 seasons from in and around my house before I dared plant any nice bushes where it once was. Mulch helps a lot too. The one area that was not mulched looks as bad as the day I moved in despite a gallon of roundup. It was an experiment and it failed.

Our long term strategy is to keep the plant from going to seed by weedwhacking it. I figure after 5 years the germination rate of the old seeds in the ground will go way down. I have also found that smothering it with flattened thick cardboard boxes (like appliance boxes) or thick leaves will also smother it after a year or so. I have huge patches of land overrun by this stuff so it is impossible to hand pull or herbicide it all. I am trying methods that are less toxic and can be done on a larger scale. I am going to experiment with thick black plastic next. I am already seeing that after a year of weedwhacking there are some other weeds now mixing in with the groundcover which I see as a good sign.

I live north of Seattle. I saw this plant and thought it was really pretty. I researched it, read all the negatives etc. But I had a spac...Read Moree right next to the walkway and the side of the house where not much will grow. I gave it lots of thought based on the negatives I've read and then decided this plant would be perfect. I planted the variegated Bishops weed about three years ago.
I still love the plant but cannot for the life of me get it to grow thick and lush. I even went out and bought more plants last year. The slugs seems to like it too much so I put out beer and that helped a little bit. It also does not keep other weeds at bay. In fact this plant seems to be fighting for its life in my garden.

I wish there was a triple negative. I inherited this vile ground cover with the house we bought. Rarely do I give a negative review but...Read More I simply detest this plant. We've been in this house for ten years now and EVERY year I have to dig up every single plant and pull this offensive, stubborn, stinky plant out from the roots of every one of my desired plants. It winds its insidious way into, around and deep into the center of the good plant and just when you think you've gotten rid of it, there it is again!!! Soooooo frustrating. I've used Round-Up by the gallon on it, as well as Weed-Begone. They die for the season but, like leukemia, it sits in remission under the ground and then bursts forth on steroids the following spring. It's roots crawl under 2-foot deep barriers and five-foot wide sidewalks. The only thing that will kill it is a ground clear solution but then there go all the other plants, shrubs and trees. Even then I'm not convinced it wouldn't come back the following spring. The only thing that is a close second is St. John's Wort ground cover. That stuff grew in gravel. I finally used a toxic poison on it and let the ground rest for 2 years to be sure it was gone. It was so I planted the area with no problems. 4 years after poisoning one horrible ugly yellow flower popped it's unwanted head up in the middle of the bed. Some plants should be against the law to sell in nurseries and these are 2 of them! Goutweed comes in the variegated and a plain green. I have them both. The variegated is easier to kill but the green seems impossible. This stuff is worse than Kudzu.

I bought a house where the owner had planted 1 bishop's weed varigated. At first I thought it was lovely and it spread nicely around a p...Read Moreond. Then it spread further and further creating a dense mat of roots thick and unyielding...not a simple pull up to get rid of it...digging out huge mats of roots. Finally because it bounces back like a rubber ball and spreads even further seemingly to enjoy a heavy cut out prune like that...I have now covered everything with landscape fabric although it is now pushing peeking out from underneath where the concrete and the ground meet. Gotta roundup those and hopefully this will be the end of the nightmare. Honestly unless you can contain this devil...like you would bamboo...do not plant it. You will live to regret it. True...it can be pretty to look at - this is deceptive because it looks so light and delicate...you cannot imagine the root system on this until you don't want it someplace it has gone...you simply cannot pull this up...much worse than wild buttercups which can be hard to pull up, bishops weed is impossible to pull out...as bad as IVY in trying to remove.

I see this is one of those plants with a lot of haters. I have a lot of land so am not particularly concerned with it taking over. I've h...Read Moread it planted for several years in an area that borders my "wild" area. It also borders a mowed lawn, which keeps it from coming this way. So far it has been well behaved. It looks nice, displaces the weeds, and has not spread very much. In fact I wish it would spread a little more because it really lights up the shade! I'm in Zone 5 with hot summers and cold winters so maybe it just isn't a problem here?

Often called 'Snow-on-the-Mountain' this cultivar is horribly invasive, spreading into everything with its thin white roots. The green mo...Read Morether type often appears by a reversion and out competes its cultivar, being more invasive. It takes constant digging or hoeing attack all season long and even more to kill this goutweed off. Round-Up on new, young foliage might help. If trying to save any plant surrounded by goutweed, make sure to pull out any tiny white roots in the soil ball. Just a tiny piece will start a whole colony.

I've found this to be the nightmare spreader that many others have reported. Because it invades the crowns of treasured perennials, it's ...Read Morethe weed most commonly spread from garden to garden by plant trades.

PLEASE, if you have this in your garden, warn the people you're trading plants with, if you're giving them divisions of other perennial plants from your garden. Hitchhiking roots can engulf a garden in three years. And many gardeners won't notice till after it's well established.

Because it can spread by seed as well as underground, this can't be contained by root barriers. The common variegated form often reverts to the plain green species. In some places I've seen many acres taken over by this weed.

It is possible to hand-dig small infestations, but this requires much labor and persistence. 2-4% Glyphosate can also help, but may require multiple applications.

Planting and trade is illegal in three states, including mine. Naturalized in 29 states, in the US this species is most problematic in the Northeast and Pacific Northwest.

There was a famous lawsuit in which an estate owner sued his neighbor (the landscape architect Fredrick Law Olmstead) from whose estate it had originally spread.

Our house came (in 1976) with variegated Bishop's Weed in a garden along the north wall, where it coexists with a couple types of ferns a...Read Morend some lilies of the valley. Not much else will grow there. I like the way it looks, and the flowers are a nice addition to a bouquet, so it's welcome to stay.

This plant came with our home, and while I would not purchase or purposely plant it anywhere now that I know of its invasiveness, I perso...Read Morenally have had no problems with it, and have no plans to try to eradicate it. We have lived in this home for over 10 years, and if anything we have less goutweed than we had when we moved here, as quite a bit of it died off due (I'm guessing) to dry soil.

I am in northern Indiana, zone 5, with well drained, loose, dark soil. Shady yard.

It is located in several spots throughout the yard, in perennial borders. I have pulled some up on occasion and haven't had too much problem with it taking over. It hasn't killed any of my other plants--a wide variety of perennials and shrubs. It hasn't spread to the neighbor's yard, though I have a small patch near our lot line; she asked for some years ago, before I even knew what it was, and I told her she could have some but I never got around to digging some up for her and she didn't ask again. If she asked again now I would advise her against it, but only because of the nightmare it seems to be for others.

I wonder if it is the specific cultivar that I have that makes mine not invasive. I don't know the cultivar name, but it is the variegated form.

As I said, I wouldn't plant it on purpose, but honestly, in the springtime, it is quite a lovely plant, and works nicely as a ground cover in our shady yard.

I did a bit of research, and it seems its mode of spreading is by its root system. Since it doesn't seem to be a threat of spreading by seed, and since I don't live near any wild areas that would be threatened by it, I have no intention of trying to eradicate it here. If my home bordered a wild woodland or meadow, I might make some effort to eradicate it in any areas of my yard that bordered the wild area, but since I don't, I am going to enjoy it.

I often get comments from visitors asking what it is and saying how pretty it is. It can get kind of shabby looking when it gets really dry and hot, but if the soil stays moist, it is happy.

Bane of My Existence (was???)

This plant was in a large perennial bed of the house I bought a few years ago. It looked lo...Read Morevely, I thought, the first year. Turned out to be the worst nightmare that others have described with spreading and choking out all other plants around. Pulling it out didn't help, as THE ROOTS ARE ALWAYS THERE SOMEWHERE & THEY WILL GROW and I shy away from poisons. I ended up hiring a landscaper to come dig out the whole bed (plus a little extra around the perimeter) to a depth of approx 15 ". No plant life of any kind was left when they were done.

I saved as many of the desirable plants as I could (transferred to pots) and the ones that I could bare-root successfully, I re-planted in the new soil. Much more expensive route than I wanted to go, but saw no other choice that would let me sleep at night. I did this 'dig' in Nov in the Seattle area. Now, on 01 Mar, waiting to see what spring brings. Fingers crossed...

This is an awful, awful plant that will take everything over. I actually was able to quite easily eradicate a whole area by first cuttin...Read Moreg off the tops of the plants (weed eater, sheers, scissors) and 'painting' on a coating of full strength, undiluted, concentrated Round Up to the tops with a foam brush. This is the concentrated Round Up, not the ready to use type formula. By applying it to the freshly cuts tips, it soaked in to the roots very easily. It is nearly impossible to kill otherwise. The solid green does not spread as quickly as the verigated.

It have seen tracts of beautiful woodland taken over by this monster, with all trace of native wildflowers forever eradicated. I lost a stretch of beautiful border along a brook to this pernicious beast, and I almost cried as it swallowed a beautifully established bed of vinca, cimicifuga, and siberian iris. Those who are happy with it either live surrounded by concrete, or they have little else in their gardens that they care about. Be considerate of others, please and NEVER knowingly plant this thing. Petition all garden stores to stop selling it, too.

I had mistakenly planted it about 3 year...Read Mores ago along the back edge of the bed.

This house is ours, but we are the landlords now and over the past 3 years, this plant has overtaken that bed ~ killed some creeping phlox and was choking the rhododendron! I was upset at the renter because I had specifically told her to keep an eye on it...but then I just became mad at myself...why would you trust a renter to listen and actually do what you asked?

It is a pretty plant in a controlled area, but don't let it go beyond that!!!

I've irradiated the all green version of this from the house we live in right now and it has not come back in over 2 years (knock on wood). So, as long as you are diligent with pulling this every time you see a leaf popping out of the ground, it will go away. No poisons required.

I have searched online for an hour and I finally figured out what it was I was watching take over my flowerbed.

I can't believe it is for sale in nurseries and garden centers! Buyer beware! I plan to stick to native species from now on...

Over the years I have now taken plants from that area and added it to 2 other areas where so far it has not really been to hard to contain. 2 are total shade and one is where it gets sun from 1pm till dusk and this one seems to be growing much faster, taller and spreading better then the 2 shade ones. I really do like this plant, it adds color, grows where you know nothing else will due to the shade and dry soil which is where all mine are currently residing. I plan on taking sections of the sun one and moving them to one side of my driveway where it's all shade, it's 180ft long strip where nothing but Garlic mustard, burdock and buckthorn along with all those other little weed trees like to grow reside. I hope it makes a nice green and white carpet to brighten up the space. Check out my photos of my sun area with this ground cover..

We moved into this house in 1989. The summer of 1990, there was this green and white plant that grew in the left side of my front yard. ...Read More Its surrounded by Caragana, a cenemt path, stairs, and the portch foundation. Only today I decided to look up " snow on the mountain", and that lead me to here.

Also, about 10 years ago, we were givin done divisions of iris, and put it on the north side of the house, that had some of this in the clumps, which is almsot 100% shade.

Neither of these have spread in my area. Whether its by the way they are some what contained, or just the climate, in NW ontario, it doesnt seem to bad.

The pollinating insects love the flowers of this plant. IT hasnt choked out iris, bamboo, or bleeding heart, or the caragana ( the caragana hedge is thought to be about 50 years old).

I cant give this plant due to the fact that its obvioulsy invasive, but I also cant give it a negative, because ive had no problems in 20 years here.

I don't know if someone planted this at some point or if it just accidentally ended up in my yard, but it's impossible to get rid of. Please be considerate of any future tenants and don't plant this plant. It's virtually unkillable and causes 10 times the maintance a yard would need without it.

Just to make a distinction - the variegated form of Aegopodium is far less invasive as the green species form. That said, it's still a no...Read Morexious weed that is best left out of the garden.

I'm a professional gardener and I run across this plant all the time. Control can be very difficult, but with time it can be controlled.

Aegopodium laughs at Roundup. If you go with an herbicide I recommend using Ortho's Brush B Gone. Important note: Brush B Gone and other strong herbicides travel through the soil and remain there for a long time (45 days or longer depending on product). So keep this in mind if using - you're committing yourself to not planting anything in the area for a long while.

After a few sprayings I mow the tops off the plant with a lawnmower. I then cover the area with a plastic tarp (green or brown, and NOT landscape fabric or any other porous material) and pin it down. The idea is here is to both dry out the root zone AND to let the sun cook the plant. It is a lengthy process, but it's a good start. If you're averse to herbicides you can simply mow the tops and apply the tarp - it will take longer to control, but it will help.

I planted 4 of these plants several years ago in a dry, shady area under some large poplars. The soil is rocky and nothing grows there e...Read Morexcept hosta, after digging up the rocks and adding compost. I thought an invasive groundcover might be just the thing to cover a problem area about 25'x25'. The bishop's weed has survived but it really hasn't spread. I still only have the 4 plants I started with. I think it looks fine but I'm a little disappointed it didn't spread a bit more. It also goes dormant fairly early in the fall, leaving a bare patch. I'm going to try vinca next.

As a beginning gardener, when I first noticed the seemingly civilized variegated form of Aegopodium podagraria growing under my neighbor'...Read Mores fence to fill the narrow shady strip behind my house, I was pleased. Four years later, I just pulled out a gorgeous lacecap hydrangea and two huge (5+ feet) sword ferns lost to this AWFUL plant. Actually, my husband pulled them out - I couldn't watch.

The roots of this weed, which is now almost entirely reverted to its vigorous green form, insinuate themselves in and around those of any other plant within reach, making it impossible to eradicate without also removing "good" plants. In the shade along my fence, it grows to 2+ feet, smothering anything within reach and easily surviving our Oregon summer drought.

Once a rabid "organic-only" gardener, I have been driven to drown this weed in Round-Up. Our current plan is to cover it in black plastic sunk into 1-foot trenches, topped with as much mulch as we can afford. However, having seen this plant grow right through weed barrier like it wasn't even there, I'm not too positive about our chances.

I purchased and planted this after reading all the comments about it.

I removed all the plants from one of the beds and got all the roots out I could find --- they were actually attached to tree roots, and poured boiling water over the soil. I will continue to spray weed killers, but the boiling water so far doesnt seem to have hurt the root, only the leaf and stem. I hope it works, but I am not optimistic.

I had heard this plant could be somewhat invasive, but many around here seemed to have it at the side of their front entrance, so I purch...Read Moreased a small plant years ago and kept it in its container while I tried to decide what to do with it.

The opportunity finally arose when I noticed that the uncovered roots of our large silver maple were being damaged by the lawn mower. I partially encircled the maple with old stone from a barn being dismantled nearby and made shallow planting patches over the exposed roots. That left me with a bare spot on the shady side of the tree, facing our path to the back of the house. I literally placed the little plant between two large roots, and filled in the rest of the space between the roots with some loose soil I had saved from other gardening projects, patted it down firmly, and left the plant to its own devices.

That was quite a few years ago. The plant has remained in the shade of the maple, and now covers an area about two feet by one and a half feet. I suppose it might eventually move into one of the two raised garden areas adjacent to it, but so far it has not done so. If it does, however, it has only hard, dry, packed clay soil full of maple roots to explore beyond that, so I think it will go no further. It looks quite nice in the dark spot it occupies, and since it supposedly helps in some way with arthritis I have been doing a bit of research on it. The reports of how it causes rashes have given me pause, however.

There are ground covers and then there are ground covers. I consider my vinca a ground cover.

But with this bishop weed, it keeps going and going. I've put in a barrier, and I try to keep up with the seedlings. That's the best I can do. The root system spreads and spreads, whether in the full sun or some shade. It was here when I moved in and will probably be here long after the house is sold. It's a nightmare.

As others have mentioned, out of consideration for others, PLEASE don't plant this plant. I'll bet the folks who say they use it between other perennials are now sorry they did so, because the roots spread underground and go right for the base of other plants. You end up having to remove the "good plant" and wash every bit of dirt off of it and examine closely for root fragments. I wouldn't even use it as a woodland filler because it would choke out anything native. Anyone who loves this has a very unusual situation and I bet their neighbors hate it.

I went around hitting some coming up in my mulch paths with roundup, along with some poison ivy. The ivy is dead. The Goutweed lost a leaf or two.

In loose soil, you can pull/sift it out of soil by hand, with work, and with lots of coming back to catch parts you missed.

I have been spreading this tenacious plant for the 8 years that I have owned this house and I am very positive on this plant (variegatum) because I live on a half an acre that is very wooded with many deer in the area. This is a very good ground cover for naturalized woodland gardens and best of all the deer stay away from it. If you don't want invasive ground covers don't go with it, but that's what ground covers are supposed to do-cover the ground. And in a wooded area like I have it works well with Hostas and ferns.

Although I dig out the roots whenever the leaves appear, it seems to grow back with even more vigour the next time. The only solution, given to me by a friend, is apparently to carpet the area (seriously!), using old offcuts. You have to leave the carpet down for at least a year or two and it should die off. It will look ridiculous. And of course everything else in that bed will die off too, and if there are neighbours with Ground Elder it will come back - but I'm going to try it anyway!

The only reason I don't have it on the 4th side is because the street is there! However, I'm fully expecting it to eventually show up 20 years from now, via underground stolons from a mile away. If one had an unlimited budget, I suppose you could hire a landscaper to remove every valued plant from the infected area, store them for 2 years while you Round-Up/plastic mulch, & install a submerged 3 foot depth steel barrier around the property. One little leftover rootlet would be enough to start it all up again, though. I HATE this plant: reason it's called GoutWEED.

It's not as if there isn't enough warning about this thing, but I have such dislike for this plant that I had to weigh in. Add north-central Montana to the list of places where it can become a nightmare, at least in watered lawns and gardens. We have heavy clay soil, very dry air, and have been in a 6-year drought (though lawns are watered, of course, providing sustenance to the thing).

Our goutweed came with the house - had been variegated but had partly reverted to green, which is apparently even more aggressive. It was marching out into the lawn, sprouting up 10 feet from where it was "supposed" to be. We dug it all up to several inches deep last year, after I had been at it by pulling it, spraying with Roundup and Weed-be-Gone, dousing it with vinegar, and whatever other tortures I could find for 2 previous years (hadn't thought of the propane torch - that will be next!). It is like the monster in a B movie - it keeps coming back! Every time a stem or leaf pokes it head up through the black plastic and 4" of mulch we laid down, I hit it with whatever herbicide I can find.

Someone did quite a sales job several years ago in my small town. I walk around and watch the lawns all over town being literally taken over by this incredibly invasive pest. One front yard is literally half goutweed now despite repeated mowing by the owners; it started as a tidy border along the house less than 5 years ago. My neighbor (across the street, thank goodness) planted a handful of sparsely spaced sprigs late last summer - I shuddered to watch - and already the first of June she has a deep, heavy, continuous border of goutweed there. Thank goodness for the 30 feet of pavement between us!

I would beg of those of you who like it: Please, please consider the next person who might live in your house, as well as your neighbors, before you ever plant even a molecule of this thing. You might be sentencing someone else to years of strife unless you plant it somewhere that is absolutely, fully, 100% contained (like surrounded on all sides by bomb shelters). I would also strongly urge nurseries and other suppliers to provide this plant only with a big red warning tag, so people know what they're getting into when they purchase it.

I find this plant to be a refreshing color addition to my shade garden.

It does very well in the dry shade of our high altitude area and only requires water maybe twice a week in the hottest part of summer. I've never had a problem with it overtaking any other plants except pansies but it does tend to spread (invade) rather well. I started with 4 plants ten years ago and they've spread probably 30 feet. I can definitely understand why other gardeners may not like it but in my case it is just fine. Kept in bounds by a garage on one side, a concrete wall and edging timbers. Does spread under pavers, low rock walls and boulders.

As an inexperienced gardener, I planted this pest to fill in as a ground cover. (yikes!) The plants spread like wildfire and I am still t...Read Morerying to kill them off. The plant smothered out all of my desired and/or treasured additions. I have tried digging it out - it just comes back with vigor. Last fall I sprayed the entire bed with Round Up.

Blooms early to mid June in my garden.

My parents have both this and the green variety growing at their place. It apparently started about 20 years ago when friends donated pl...Read Moreants. The green form seems to be significantly more invasive.

Make no mistakes, this is a serious pest for any climate that gets regular rainfail or moisture. Even if you think you have it contained, over a few years it will find a foothold in lots of places. It will escape and take over. This is a gradual, but relentless, process.

Several years ago, I took over the outside work, and started to wage a campaign against this weed. It is everywhere, and there are places in the lawn where it has destroyed all the grass.

This year, I have finally found a strategy that eradicates it from specific areas here, but since it is so omnipresent at my parents', I doubt I will ever eliminate it from the whole property.

To kill it, start in the spring after the plants have emerged but before they get to full size. Use Round-Up, the formulation that spreads through the plant and attacks the root. Spray weekly (and throughly) for several weeks. Do not pull or disrupt the plants for the first two weeks. After two weeks, which gives the Round-Up a chance to circulate through the plant, I use a weed-wacker to take the plants down to the ground. I then wait at least several days, then when new growth starts, apply Round-Up again. A couple of cycles of this should eliminate most of the plants. I then till thoroughly and apply Round-Up about a wekk after tilling.

I have one bed this sumer that is now free from this pest, and so far it has not come back. Of course, this would not work if you have other plants in the area you want to clean.

I have also noticed that it is helpful to keep the area that you are trying to cleam up as dry as possible.

This stuff is found in most yards as a weed throughout my area. I see it everywhere, even at places 100's of miles away. In my opinion, having seen this plant at work over some time, this pest is not controllable over any extended period of time. Please be environmentally responsible and do not plant this anywhere. Take the test: If you think this is contaned at your place, try removing it for a season. You will find it growing someplace you did not think it was, and you will find that you did "not" remove it when you thought you did.

I have a client that, when I took over the account 3 years ago, was infested with this--- I have turned the gardens on their heads, weeding the rootballs of the plants,( the root of this weed is easy to spot) and after 3 years of diligence, I am happy to report that I am winning the battle. If anyone wants to try this, here are a few tips.... keep in mind that aegopodium likes to grow in the top 4 inches of soil, so don't dig too deep when getting it out. you will undoubtedly miss a few rootlets, just dig them out as they show up, and be persistent! Edging does help, as it will allow you to work smaller areas at a time without worrying about re-infestation from surrounding areas (nothing is easier than nice fluffy soil) I am going to try a heavy dose of round-up just before dormancy, that may be the key. Oh, yeah.... don't try to compost this stuff, it will spread, no matter how deep. DROWN IT! put it in a barrel, cover with water, do not allow light.... stinks like crazy but is the only sure way to kill it Good luck!

I had no idea what caused the break out the first time I tried to go after this plant. Now I know. I had to expose myself to this plant again when it resprouted after I had tried to dig up the area in which it had been growing. I got that horrible rash again. No where near as bad of a rash as what one would get from Wild Parsnip but bad enough to make one totally miserable. By the third time I went at it, I had made the connection that the Aegopodium was causing me to break out in a horrible rash. I lubed the area of my arms above where the gloves were with a product called "Oak-N_Ivy Tecnu". I went at the Aegopodium for about an hour, came in and added more Tecnu and rinsed thoroughly and had no outbreak. If anyone chooses to go after this plant by pulling it up, you might want to consider Tecnu for any exposed areas of your skin.

Digging out the entire area in which this plant was growing followed up by hand pulling any resprouts should eventually get it.

My best effort was in a bed I hit with Round-up repeatedly, killing everything vegetative, then mulched heavily. It still resprouts, but at somewhat controllable rates. It has spread everywhere in my garden and lawn where the soil has been disturbed. It will not grow in undisturbed hard-packed clay, however. Surprisingly, it does not grow in the woods where I cast uprooted plants. The sheer volume of biomass this plant produces are impressive. The flowers are pretty, and I try to pick every one to prevent spreading by seed--which is prolific and has a high germination rate in my beds. Sometimes seeds form on the cut flowers in vases! It also spreads by massive quantities of crisp white runners proliferating even under boulders and other inhopitable obstacles, to whatever depth the soil has been worked. It sprouts in the middle of hostas, daylilies, etc. and wraps itself around iris corms. When I have divided perennials, it hitchikes on the roots and sprouts from miniscule overlooked threads. The runners soon result in new corms or nodes that send out new runners that can grow several yards in a season. It thrives in sun and shade and especially in moist places, even infertile ones. It resprouts after the first hard frost and before the spring bulbs are in bloom. Handpulling it only reinvigorates it. Do I sound embittered and battle-weary about this one? I am!

POSITIVE: I have only found mosses growing beneath goutweed once it has become established. A neat and tidy line is easily kept when goutweed is used as a bordering groundcover to a lawn...the repetative mowing keeps it from spreading into the lawn. I have not observed it spreading by seed, but vegetative propagation is easier than willows.
