It's either "Soft Blue" or "Caesar's Brother" but the one I have definitely looks blue on the camera, but to the eye it looks purple.
So beats me which one it is! I just know it's a Siberian Iris.
There's another one yet to bloom and I have no idea what color it will be. This is their 3rd year in the ground and just now starting to bloom. The previous years they were so small and didn't bloom (out of a set of 7 roots, only 4 survived and I got a refund) and it hardly seemed worth mail ordering them and I definitely recommend visiting a local plant nursery instead to get a well established clump in a pot. Mail order live plants tend to be teeny tiny and take forever to get established. At least you won't have to wait three years to see what you purchased!
