Hibiscus

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.

It is widely grown as an ornamental plant throughout the tropics and subtropics. However, plants in containers may be placed outside during the summer months or moved into shelter during the winter months. (Source: wikipedia.org)
