This iris bloomed four different times for me last year. It multiplies really well and its blooms are prolific. Mine gets morning sun and afternoon shade and is thriving. Pictures can't really do justice to this flower.

This iris has increased well for me. I have it growing in a bed that developed some bacterial rot in some of the iris. This iris developed rot, but with treatment it is coming back as strong as it was originally. Many others succumbed to rot.
