I got purple loosestrife years ago and I really love this plant yet it's deemed invasive and banned in certain areas. Sad because the bees love it. It has not become aggressive in my garden but then I haven't given it it's optimal growing conditions of wet soil. Seems to like marshy areas and the like. Then I got it's relative Gooseneck Loosestrife. Good grief! what a beautiful plant. what a pain in the ass to get rid of. That plant spread like crazy and took over and bullied out half of the large bed it was in. I sadly had to remove it. Took about 3 weeks of digging-after work-and digging and digging. If I see it for sale again I'd get it and use it in a container. the same with tradescantia. I like it but it comes up unwanted everywhere. Thats another candidate for a container. kudzu-hate it. trumpet vine-love it but I can see why it could be invasive but worth the keeping for the hummers. But keep and eye on it. Dewberry if you can manage the vines and keep the seedlings in check then I say go for it. better than looking at a concrete wall.
