I bought "Chicago Royal Crown" in a pot from a local nursery in May of 2007. Its first bloom for me here in Northern VA was June 22nd. I know the AHS database calls it "Early", but for me, it's more of a "Mid-Season". That being said, it was a stellar performer in the garden its first year, blooming vigorously over a period of over three weeks. The flowers were large, a very deep rosy-purple with a darker eyezone, and held up well in the sun.
