This variety survived being abandoned as far as care goes, in the open Canadian prairie. Came back and dug it up out of the grass four years later, and it is now growing and blooming true in a cozy yard in the city! Truly a hardy variety!

This is one of my very favorite SD iris. Prolific grower, and blooms and blooms!

The self color can vary, for some reason, leaving some blooms nearly white with the contrasting rich blue beards. The rebloom seemed much more blue-a sky blue. Nevertheless, I would recommend this iris to anyone.
