This is one of the best plants bred by Griffeth Buck.  It is very shrubby to about 5x5', and is almost always covered in light apricot blooms.  The blooms are pretty pale in the hottest weather, but when it's cooler they are a beautiful shade of apricot.  There is some fragrance and very good black spot resistance.  Bred in 1985, rated as hardy from zone 4.
