Whoa! It really is blue! Lavenderish blue rather than sky blue, but still definitely BLUE. I'm delighted with the color and form of this iris. This is its first year, so I've only gotten one scape, but it bears several buds. The first bloom opened yesterday, which puts its start about a week later than most of my mid-season irises here in Atlanta.

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.
