Overview
Hibiscus syriacus 'Aphrodite' is an upright deciduous shrub reaching 8-12 feet (2.4-3.7 m) tall and 6-10 feet (1.8-3 m) wide at maturity, with a vase-shaped habit broadening with age. Leaves alternate, three-lobed, 2-4 inches (5-10 cm) long, medium green, emerging in late spring after most other deciduous shrubs have leafed out. Flowers single, deep rose-pink with a prominent dark red central eye and red veining radiating from the throat, 4-5 inches (10-13 cm) across, opening from midsummer through early fall. Each flower lasts a single day; new buds open daily over a 10-12 week bloom period from July through September. As a triploid selection, 'Aphrodite' produces few or no viable seeds, reducing the volunteer seedling problem associated with diploid H. syriacus cultivars. Growth rate moderate, adding 12-24 inches (30-60 cm) per year. Cold hardy to USDA zone 5b (-15°F / -26°C); top dieback may occur in zone 5 winters and the plant rebounds from the base. Late spring frost can damage emerging foliage, delaying bloom by 2-3 weeks.
Native Range
Hibiscus syriacus is native to south-central and eastern Asia, including India, China, and Korea, growing in mixed scrub and forest edges at low to mid elevations. The species has been cultivated since at least the 16th century in Europe and is naturalized in parts of the southeastern United States. The 'Aphrodite' cultivar was bred by Donald Egolf at the U.S. National Arboretum and released in 1986 as part of a series of triploid H. syriacus selections.Suggested Uses
Used in mixed shrub borders, as a specimen, and in foundation plantings at 5-7 foot (1.5-2.1 m) spacing. Planted as an informal hedge on 5-foot (1.5 m) centers for a continuous bloom display from midsummer through fall. Suitable for containers of at least 20 gallons (76 L) with adequate drainage; container plants reach approximately 60% of in-ground mature size.How to Identify

Bloom Information
July through September in zones 5-9, with peak bloom in August in zones 6-8. Flowers open early in the morning and close by evening, with each flower lasting a single day. New flowers continue opening daily for 10-12 weeks. Blooms set on current-season wood, so bloom timing is unaffected by winter dieback.

Care & Maintenance
Care Guide
Water deeply weekly during the first growing season, applying 1 inch (2.5 cm) per week in the absence of rain. Established plants tolerate moderate drought but flower production decreases during prolonged hot, dry periods. Fertilize once in early spring with a balanced fertilizer at the rate listed on the label. Aphids cluster on flower buds and new growth in early summer; lacewing larvae and ladybugs typically suppress populations. Japanese beetles feed on leaves and flowers in July in eastern regions. Plants live 20-40 years in suitable sites.Pruning
Prune in late winter or very early spring before bud break. Cut back the previous year's growth by one-third to one-half to encourage branching and larger flowers. Remove dead or crossing branches at the base. Hard rejuvenation pruning to 12-18 inches (30-45 cm) above the soil line is tolerated and produces a flush of vigorous new shoots, with bloom returning the same season.Pruning Schedule
