One of the first plants I noticed and learned the name of. This is Midland, Texas, out in West Texas, zone 7. Did well there and not as invasive as in the southeastern U.S. The photo of the plant in D.C. reminded me to inform that this species is not invasive everywhere. D.C. is just cold enough (and warm enough) to create a well-behaved tree. As always it depends on site and climate as to whether a plant is a weed. The northern Florida experience written about above is an example of the wrong place! The Cercis should do very well. And, it is another legume!
well done discussion of the tree.
I don't know if Mimosa has made the Maryland invasive list--but my neighbor had a big one. Everything the author says about the tree is true. That tree died (wilt?) quite a while ago and I am STILL dealing with seedlings that lay dormant under my bushes until the bushes were trimmed and the seedlings got enough sun to take off.
