Chrysophyllum
Family: sapotaceae
This genus consists of around 80 species of evergreen, tropical trees mainly from the Americas, although some species also occur in West Africa and Australia. Many have edible fruit, while some are grown for their fine timber.
Species
C. cainito, star apple or cainito, grows 12-15 m (40-50 ft) in good conditions. This handsome tree has glossy foliage and smooth, purple to pale green fruits, with white, edible flesh. The star shape is evident when the fruits are cut transversely.
C. oliviforme, known as damson plum in Jamaica, is native to tropical America. It grows to 10 m (33 ft) and has small, purplish fruit.
Cultivation
In frost-prone climates, grow as pot plants in a warm greenhouse. These trees prefer fertile, deep soil, with plenty of organic matter. Water regularly throughout the warmest months of the year. Propagate from seed or from cuttings if bottom heat is available.
