Jatropha integerrima

Jatropha integerrima, also known as Peregrina and Spicy jatropha, is an exotic and flowering bush highly appreciated in tropical and subtropical regions. It can only be grown in open ground in very mild climates, as it is frost-sensitive at -3°C (26.6°F). However, it is perfect in pots to overwinter in cooler climates. Forming a bush with several erect trunks, from spring to autumn it produces lovely red flat flowers, gathered in tight inflorescences. Evergreen in mild climates, it tolerates occasionally dry soil and needs full sun in summer.

Jatropha integerrima belongs to the Euphorbiaceae family, and like euphorbias, it produces an irritating sap. It is a botany species native to Cuba, Dominican Republic, and the Antilles that has naturalised well in tropical to subtropical regions, particularly in Africa or India. It forms a bush with several trunks, and well ramified and downy branches. It has a slow growth rate. In pots, it reaches from 1 to 3m (3 to 10ft) in height. In its native region, it reaches up to 4m (13ft). It will flower all year round in tropical climates; elsewhere, flowering takes place between spring and autumn. The flowers, 1.5 to 3cm (1in) wide, are grouped in tight inflorescences, where several male flowers surround 1 or 2 female flowers. The flat flowers, with 5 fused bright red petals, are very bright. The foliage is evergreen in winter in a heated greenhouse, but is deciduous in a cool room or in open ground. It consists of dark green leaves of rather variable shape, with a cordate base, oblong to ovoid shape, and entire to divided into several acuminate lobes. They are alternate, carried by a petiole 5 to 8cm (2 to 3in) long. 

Jatropha integerrima is a bush with exotic charm and generous flowering. In very mild climates, it can be grown in the ground. Elsewhere, plant it in pots and place in full sun from spring to autumn. Bring the pot inside to a room of 15°C (5°F). Alternatively, place in a heated greenhouse where it will grow all year round.
