Rose of Sharon

Brief Description

An upright, deciduous shrub or small tree with dark green, palmate-lobed leaves and large, trumpet-shaped flowers featuring prominent stamens. This specific specimen appears to be a double-flowered cultivar.

Care Instructions

Thrives in full sun and well-drained soil. Water regularly until established, and feed with a balanced fertilizer in early spring. Prune in late winter to maintain shape and encourage larger blooms.

Medicinal Value

We do not currently provide medicinal value for plant identifications.

Sunlight

Full sun (6+ hours per day) for best flowering, though it can tolerate light partial shade.

Watering

Moderate; requires regular watering to keep the soil moist but not soggy. It is moderately drought-tolerant once established but may drop buds if too dry.

Soil

Prefers rich, moist, well-draining soil with a pH of 5.5 to 7.5. Adapts well to various soil types including clay.

Hardiness Zone

USDA zones 5-9

Growth Habit

Deciduous upright shrub or trained as a small tree. Reaches 8-12 feet tall and 6-10 feet wide with a moderate growth rate.

Bloom Season

Summer to early Fall; flowers can be white, pink, red, purple, or blue, often with a contrasting dark 'eye' or double petals.

Toxicity

Generally considered non-toxic to humans, but the ASPCA lists Hibiscus syriacus as non-toxic to dogs and cats, though ingestion may cause mild digestive upset.

Propagation

Easily propagated by stem cuttings (softwood in summer or hardwood in winter) and by seed, though seeds may not come true to the parent cultivar.

Common Pests & Issues

Aphids, Japanese beetles, and whiteflies are common pests. Susceptible to leaf spot, rust, and canker if air circulation is poor or soil is overly wet.

Similar Species

Hibiscus rosa-sinensis (Tropical Hibiscus) has glossier leaves and is not cold hardy. Hibiscus moscheutos (Hardy Hibiscus) has much larger flowers and dies back to the ground in winter.

Interesting Facts

It is the national flower of South Korea. It is highly valued for its late-season bloom when many other flowering shrubs have finished for the year.
