The flowers are borne in rounded corymbs of 6'-8'. In harsh weather, such as wind and rain, branches bearing flowers bend to the ground and should be staked. The flowers easily turn light blue on acid soil, but are pink in more alkaline soils, despite the plant's "blue" reputation. It is a hybrid between 'Otaksa' and 'Rosea'.
