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.

    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!

    I have to say that I love the gooseneck loosestrife I have had for quite a few years. I first say it on the very shady side of a friends house. It was a great ground cover in a place nothing else would grow. It was bordered by the house on one

    Do not plant valerian. It sends underground runners, just like wild privet. The older it gets, the taller it gets. Watch out for rudbeckia and echinacea as well. Oh yeah, let's not forget Montbresia!

      I have found that these guys need to be planted in pots with a barrier under the drain hole of the pot. Then all you have to worry about are the seeds and deadheading stops that.

    Don't ever plant Mexican Firebush. It is beautiful but will take over your whole yard
