I love Mokan Butterfly, I purchased it in an end of season sale. I wasn't sure if it would even survive the winter it was in such rough condition. The next year it did come back and had a couple of blooms even though we were in a severe drought. This year it has come back and looks fantastic, (waiting for scapes) with all the rain we have had so far. This one is a fighter and has a place forever here in my zone 5 garden.
