I'll have to ID that plant when I get home this weekend. Am sitting in the 'Point' brewery taproom (Stevens Point, WI) right now, wetting my whistle on my way to camp in northern WI to chase brookies for a few days. That spot on our property gets loaded with them on certain days during the fall migration in Sept/Oct if we get a decent cold front/steady north wind fetch; usually neo-tropical songbirds with them, too.
