Hibiscus

Hibiscus syriacus (hi-BIS-kus seer-ee-AY-kus)

Family: Malvaceae Non-native Shrub (3-15 ft)

Rose of Sharon is a rapidly growing, large, deciduous shrub or tree in the Malvaceae (mallow) family and native to south China and Taiwan. It grows to 8 to 12 feet tall and 6 to 10 feet wide, so consider its space requirements when determining its planting location. Plant in locations with full sun to partial shade. It is tolerant of neglect and is pH adaptable. It grows best in moist, well-drained soils but is tolerant of all except extremely wet or dry soils. It prefers hot weather. Spring pruning will encourage flowers on new growth and will increase flower size. The plant is moderately tolerant of salt, deer, heat, and wet soil. Plant in a children’s, pollinator, or butterfly garden. Plant in multiples 6 to 12 feet apart to create a hedge. Flowers are an attractant for butterflies, specialized bees, hummingbirds, and pollinators and are a wildlife food source. Quick ID Hints : large, tropical looking, 5-petaled flowers erect, spreading habit with upright branches 3-lobed leaves are 2-4 inches long simple, alternate, coarsely toothed leaves 5-valved, dehiscent capsule persists thru winter Insects, Diseases, and Other Plant Problems: Rose of Sharon has been reported to be invasive in some states, including Virginia and Kentucky.
