Found this growing in various places in my backyard in St Paul, MN. It hasn't flowered yet, so no help there. It's sparsely branched, seems to be doing best in shady areas. Stem is thick and quite stiff - not woody, but almost bamboo-like.

I have another picture that shows the plant in its native setting (contrary to appearances, this specimen did not grow on my stove top). Looks like I can't attach a second pic. I suppose I need to set up an account on the Flickr or something.

Thanks much!
