You guys are awesome. That is it. A bird must have brought it in. Sure was a big surprise when I noticed this tiny little seedling starting up in one of my raised beds that has peonies and Blackberry lilies. I have never seen one of these around here though. Can't wait until next summer when it will hopefully bloom.
Mine is also growing off to one side, good to know it might start sending growth straight up. It is already branching.
