Some California bred iris haven't done well for me; they seem to never adjust to Michigan's climate. And I wasn't really thrilled when I got this as a bonus since I didn't care for the dark tops at the time. My opinion has completely changed. WS took a season to adjust, then took off and has grown steadly. Beautiful clear colors which show up from a long way off in the yard and about the prettiest form of any iris I've seen. A winner.
