I have the same "tree" in the ditch as the original picture in this post and I think the leaves look sumac-like. The hogweed has fern-like leaves. Based on that, what do y'all think we have here with the Queen-Ann_lace flowers and Sumac-like leaves?

Thanks! My dad thought it might be what they used to call "nutvine." I guess he must have meant groundnut!

Globe Thistle (Echinops)

I used to grow blackberry lilies in Georgia and they bloomed right through the summer we couldn't water at all. However, I've read that the seeds don't germinate. It spreads like iris, which it is, according to the site Ginny provided.
