Get an incredible color and variety mix that contains single and double bloomers. Rose-of-Sharon Hibiscus is valued for large flowers produced in mid-to late summer when few other shrubs bloom. The plant grows in sun or partial shade and in any soil. The growth rate ranges from slow to moderate, and transplanting is easy. The single or double flowers are in shades of red, pink, white and purple, depending on the cultivar. Peak bloom takes place in August. Prune in late winter or early spring. Frequent severe pruning gives fewer but larger flowers; no or little pruning gives many small flowers.
