Hibiscus rosa-sinensis 'Zephyr' (Zephyr Hibiscus)

Hibiscus rosa-sinensis, commonly known as Chinese Hibiscus, Tropical Hibiscus, or Chinese Rose, is an evergreen shrub or small tree in the Malvaceae family. Its exact wild origin is uncertain, and the species is considered an ancient cultivated plant, probably derived from tropical Asian ancestors and spread throughout the tropics centuries ago. Plants typically grow 6-10 feet (1.8-3 m) tall, occasionally larger, with glossy, toothed green leaves and a dense, branching habit. The large, showy flowers may be single, semi-double, or double and occur in an enormous range of colors, including red, pink, orange, yellow, white, and numerous multicolored combinations.

In warm climates, Hibiscus rosa-sinensis can flower almost continuously throughout the year, with individual blooms usually lasting only a day or two but being produced in rapid succession. It grows best in full sun to partial shade and fertile, well-drained soil with regular moisture and feeding during active growth. Pruning encourages branching and helps maintain a compact, floriferous plant. Hardy in USDA Zones 9-11, it may suffer significant dieback during freezes in Zone 9 and benefits from a sheltered location and cold protection. In cooler climates, Tropical Hibiscus is one of the most popular flowering houseplants and container plants, valued for bringing its spectacular tropical blooms indoors. Thousands of cultivars and complex hybrids have been developed, making it one of the most diverse and widely grown flowering shrubs in tropical and subtropical gardens as well as a favorite indoor ornamental.
