Sporting by far the largest flowers we have ever seen on a Rose of Sharon, this multi-stemmed shrub will bowl you over with its beauty. The lavender blooms are simply massive, and arrive in great numbers, standing out brilliantly from the dark green foliage. A showpiece of a shrub, Full Blast earns its name with super-fast, vigorous growth from the very first season. Eventually reaching 8 to 10 feet tall and wide, it puts on about 3 feet a year if pruned back annually. Deer leave the plant alone, which is one big reason for its success. Another is simply a more robust nature, which rewards you with better branching and more blooms, season after season. The flowers begin in early summer in most climates, as soon as the hot weather arrives. Butterflies cannot resist their allure, adding to the beauty of the garden. Hibiscus 'Full Blast'
