Blonde Vision doesn't seem to have a problem with weak stems as far as I can tell in my garden but it certainly has a problem with a weak constitution! The buds and the stems are so cold intolerant that it's hard to believe this thing is a peony—seems more like a tropical plant! I've only had it perform fairly well 1 year out of the 8 or so that it was in my garden. It's in AL now, sure hope it does better there because the bloom is so pretty when it manages to open with no damage.
