Invasive plant horror stories

Hometalk member and gardener extraordinaire Barb Rosen recently wrote of her nightmare experience with chameleon plant, Houttuynia cordata, and what may be her life-long project of getting rid of it. But Barb surely isn't alone in having planted something she regretted. For me, my biggest mistake was planting gooseneck loosestrife, Lysimachia clethroides. I'd heard how "rambunctious" the plant could be, but I had a dry, shady spot where I couldn't get anything else to take hold and bloom. Well, the lysimachia did, and soon started looking for territory to annex. I've since sold the house and it may have taken over the entire property by now for all I know. Here's your chance to sound off and put up the warning flag about plants that belong on a "do not plant" list. Please post a photo if you have one, and let us know what zone you're in.

    Snow on the mountain - is taking over and is almost impossible to eradicate. I still see it being sold in garden centers even though in some areas it is considered a weed!

    OMG thought I got rid of gooseneck loosestrife 10 years ago but found in garden this summer, not even close to where I had it before. I blame birds and wind. NASTY stuff

    Chameleon vine/plant....what a nightmare! These connecting roots take over and smother other plants. Hard to get rid of....the smallest piece of root will make new plants if you don't get all of it. I'm in zone 6a. Beware!

    I finally won my battle with Alstromeria. Very invasive, insidious and persistent. Even after spending hours digging up a large bed and hand-removing little bulbs, I still see a sprout popping up from time to time. Mine was a pass-along and probably the

    My mother-in-law planted trumpet vine next to her house and it grew under the siding and into her basement which had a dirt floor. The vine even found its way in between the windows on the porch.

    I also have the Gooseneck Loosestrife, but I think I'm finally winning the battle with it. I only saw a couple of small sprouts of it this spring, and I nipped it right in the bud. Two plants that I do have a lot of that has become invasive is Obedient

      Miss Kitty Those bellflowers are awful. It took me 3 years of digging and sifting through dirt to find every last piece of running root. Three small plants took over everything!

    Wisteria. I didn't actually plant it; it invaded from a neighbor two doors down the street. The underground growth went all the way back to her property. After a fight of nearly 10 years, attacking from both sides WE FINALLY WON!

    Campanula "Elizabeth" is very invasive, even though it blooms from spring to fall, I have had to have at it consistently to keep it from overtaking all the beds!
