Also known as Red Ballerina, this one also has many small blooms in large mophead clusters like a hydrangea.  The blooms are a cheerful bright crimson with glowing white centers and are very striking. The contrast in colors makes this plant add texture to the landscape.   The plant grows wider than it is tall - it can be about 6' wide and 4' tall.  It could look nice cascading over a wall.  It has average disease susceptibility and pretty good rebloom.  Bred in 1977 by Harkness.  Hardy from zone 4.  It received three gold medals and several other awards as well as Copenhagen First Prize.
