Very hardy plant which sprouts late Spring and by the beginning of summer has exceeded 6 feet in height! Be prepared for the size of this monster, and for lots and lots of offspring if you don't remove the bountiful seed pods at the end of the season, before they pop open. The leaves are more maroon the more sun it gets, in part sun they are green with a strong tinge. Not suitable for my small specimen garden but I have to rate it positive anyway before I try to move it.
