All Summer Beauty has large mophead flowers which are blue in acid soils and pink in alkaline soils. The mophead inflorescence consists mainly of showy but sterile florets with a sprinkling of fertile florets around the outside. It grows 3 to 4 feet tall, blooming in June until fall with bright green foliage. It blooms in mid summer on new wood, and later in the summer it will bloom on old growth until fall. It is winter hardy to USDA Zone 5, but for added protection the plants can be sited in a sheltered location and given a good mulch and/or covered with burlap for the winter.
