Invasive plant horror stories

542K Views
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.

    Tansy in New Jersey! The label said it would be 12-18" high. Try 48-52", and 4 years to finally eradicate it by digging up the roots whenever it showed sprouts.

    I use white vinegar and dish soap in spray bottle to kill plants in cracks of stone walk and patio.

      with invasive plants, it might be best to dig up the plants yo want to save and move them to another spot then dose the offenders with vinegar and soap, maybe even salt.

    Mint plants MUST be grown in containers! Playce fine screen mesh in bottom and place container up off ground so u can check for roots wandering out.

      I had a mint garden and golden rod started growing in it. Within 2 years all of the mint was gone and golden rod is everywhere

    I made the mistake of planting chamelion plant. After one year, I realized I made a mistake. I have sprayed with a glycophosphate vegitation killer... twice and have over the past four years dug through the soil of that garden whenever I find a sprig

      A friend found this out the hard way, it is advertised as a groundcover and boy does it cover!
