I was after a very blue Iris and had reserached this site, gardening blogs, etc; to find what types others thought were the bluest. This one was one that was listed often and I am very happy with the color. Yes, it is an absolute treasure. It's tall. It's at approx 36" and this is a first season blooming. Planted Fall 2013 and Bloomed this Spr 2014.
