Cultivated throughout the world as an ornamental, in the tropics and subtropics in the open, often for hedges. The origin is uncertain, but possibly from East Africa.
The leaves and flowers are used to ripen boils and ulcers, and in general as an antiseptic. The flowers and bark are considered to have emmenagogic, galactagogue, purgative, even abortifacient properties. In Papua New Guinea, the roots are washed and chewed to treat diarrhoea.

- Leaves ovate, 7-12 cm long, margins coarsely toothed, upper surface glossy; epicalyx with 7-9 linear lobes, calyx 2 cm long, bell-shaped, with ovate lobes.
- Flowers about 10 cm in diameter, petals normally red, sometimes orange or white, staminal tube slender and longer than the corolla, red, anthers yellow, stigma red.
