Hibiscus rosa-sinensis is a bushy, evergreen shrub or small tree growing 2.5–5 m (8–16 ft) tall and 1.5–3 m (5–10 ft) wide, with glossy leaves and solitary, brilliant red flowers in summer and autumn. The 5-petaled flowers are 10 cm (4 in) in diameter, with prominent orange-tipped red anthers.
Hibiscus are deciduous shrubs with dark green leaves; the plants can grow to 15 feet tall in frost-free areas. Flowers may be up to 6 inches diameter. Hibiscus can be planted singly or grown as a hedge plant; they can also be pruned into a single-stemmed small tree.
