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