That sounds like a solid plan, thanks. Unfortunately for me, it is coming up all around my irises and osmanthus, so I suppose I will have to take that in account as I proceed. I have to do some major work in the bed anyway come fall, so your advice will definitely be put to good use. Thanks!

Wish I did… This is another one of those plants that you pull it all out and it’s back in a week. If I was serious about killing it, I think I’d throw an old carpet (upside down) over the bed. I have very good success with the old carpet method… When reading about these stoloniferous pests, everybody talks about putting poison on it, and then coming back several times to put more poison out… Doesn’t sound like the biocides work. Might as well skip directly to something that does… Sometimes, I’ll put a sheet of plastic down before the carpet, and after putting out the carpet, I’ll cover that with wood chips… so that we don’t have to look at the carpet… and finally… I’ll bring out my container garden… on top of the wood chips… In a couple of years… I’ll check under the carpet to verify that the invasive is throughly dead. Plants generally don’t survive in the dark.

Stone, do you have any suggestions for houttuynia cordata? I am fighting a losing battle with it in my streetside bed.

For the third picture… I’m thinking possibly Conoclinium coelestinum. Does it have blue flowers in the autumn? Middle pic might be a thornless eleagnus. Really need additional pics…

Does the white bloom belong to the top plant? Otherwise, the top one looks like Japanese Knotweed. The bottom one is Mulberry weed. The middle picture could possibly be a wild pear.

The top picture is houttuynia cordata. And… they are terrible.
