This plant is terribly invasive and destructive of whatever it clings to. I'd avoid planting it at all cost. It's very difficult or impossible to eradicate because of the prolific seeds and aggressive roots that will travel many feet underground. That's bad enough but what makes me despise it is that I get a terrible rash from it that's worse than what I get from poison ivy and that's saying something. Yeah, it makes pretty flowers and the hummers like them but there are better choices out there.

After reading all of the comments on the Trumpet Vine...we promptly are going out today to dig up the 4 we planted yesterday along our fenceline! 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.

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 application. 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.

I am EXTREMELY disappointed that Dave’s Garden would promote Campsis radicans – it is a THUG. Yes, it is a lovely native plant … but so is poison ivy.
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.

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 dealing 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 t... read morehick 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.

Despite the plant's reputation, if you want to draw in hummingbirds, Campsis radicans (Trumpet Creepers) are great choice for native plant 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.

Yes, the flowers are lovely, but this species has been too aggressive for me to control in the garden. It is native on the east coast from New Jersey south, but it's an invasive exotic species that has naturalized in New York and New England.

From Z6 south, Campsis grandiflora is a better choice for most gardeners as it is less aggressive. The hybrid between the two species is also said to be less aggressive than C. radicans and a zone hardier than C. grandiflora.

On a scale of 1 to 10, I give this plant negative infinity. I cannot express enough just how dangerously invasive this plant is.

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 rentin... read moreg, 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 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.

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.

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.

TRUMPET VINE CAN PENETRATE ASPHALT DRIVEWAY!!!

My neighbor, who has since moved, planted a trumpet vine 6 yrs. ago on our property 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 ... read moreunder 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.

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.

Trumpet Creeper is native. I can see where some may call it invasive, but I agree that calling a native plant invasive is not the correct way to characterize this plant. 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).

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.

Besides morning glories, they are a great hummingbird lure.

It seems to have worked so far on the ones that were growing up, around, and finally inside the house. Whew!

I wanted one of these for my hummingbird garden collection. Even after reading all the negative ratings, I recently purchased one. I just 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... read more 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.

These do have their place in the garden, if you can keep them contained! Ours (we have seven) have been trained into little 6-7' trees lining our driveway.

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

Invasive? Yes. Beautiful? Absolutely.

If you're into sculptured 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... read more 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!

A mature red vine was one of the selling points of the house we purchased in '02. Hummers loved it and it was a big, shady beauty on the eastside of the house and garage.

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

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.

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.

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.
