A terrific grower and heavy bloomer, it usually starts my iris bloom season and comes close to finishing it. It gets very tall for me (often reaches 52"), and has bright, orchid-like colors which show up all the way across the yard. Not every Dykes medal winner seems to deserve its award but this one deserves every honor it's received. A standout!
