I've had this beauty for a few years now and every year I'm just as impressed. It grows well (but not too vigorously) and increases well. What a show it puts on! It is as near black as I've seen in a LA iris. It gorws to 36 inches tall. (NOTE: due to it's dark color - afternoon shade may be advised in very sunny, hot climates.)
