Rose of Sharon bears many blooms, and its attractive flowers are its main selling point. Like other types of hibiscus, its flowers bear a striking stamen. Another feature giving the shrub value is its relatively late period of blooming (in the northeastern United States, it blooms in August). Rose of Sharon is thus able to offer white, red, lavender, or light blue blooms when many flowering shrubs have long since ceased blooming. Late summer flowering shrubs can help gardeners manage the sequence of bloom in their landscapes.
Rose of Sharon is easy to grow, even for beginning gardeners. Hardy in USDA zones 5-9, rose of Sharon bushes are tolerant of a wide range of conditions, including poor soil, heat, humidity, drought and air pollution. Flower colors include white, red, pink, lavender, blue and bicolors, with single or double forms.
