[MAIPC] What Is It?

[Milo Pyne]

the exotic small Polygonum (Persicaria) that we see most frequently in NC, LA, KY, TN, etc. is P. cespitosum/a var. longisetum/a (= P. longisetum/a)... and it does have long setae (long hairs from the sheath or ochrae).

I cannot discern that feature in these images; but that is the first one I would test this against.

Hi,
We are working to figure out which invasive polygonum is in the photo below.

Any ideas?

Thank you in advance,
Patricia

Hello, Claudia.

My neighbor allerted me this latest invasion of our woods. This is a small green plant that has spread rapidly, and is shallow rooted. I have tried to use my 'plant identifier' app, but got totally confused. They eventually bear a small purplish flower on a spikey stem.

Would appreciated an identification, and some advice as to how to get rid of it. I am perfectly willing to pull them all up, but would appreciate a go ahead from you.
Thanks for your help.
Margo Sterling
