Related To: [Oxalidiceae] Bilimbi, Oxalis

Main Uses: Fruit

Growth Rate: Moderate

Mature Height/Spread: To 30 feet; generally a smaller tree.

Flowering/Pollination: Small, White/purple, cauliflorous

Tolerance: Moderate tolerance for both salt and drought.

Soil/Nutrition: Widely adaptable. Fruits prolifically on soils of acidity, and fairly well on soils of alkalinity (but will tend to be chloratic). Once established, needs very little attention. Mulching and fertilization will yield copious amounts of fruit 2 or more times a year.

Light: Half shade to full sun. Leaves are photosensitive, opening during the day, and closing at night.

Wind: Small leaves and moderately hard wood make this a rather sturdy tree.

Temperature: Light freezes will damage young shoots. Trees are hardy, and will quickly recover from light freeze damage. Should be considered tropical, though mature specimens will fare quite well in subtropical locations, provided shelter from chilling winds. There are mature starfruit growing and fruiting in Orlando, FL.

Dangers: Fruits contain oxalates (as do many in the oxalidaceae family), which can promote kidney stones in certain individuals. Oxalates are concentrated in the ribs, which can be easily cut off. They are also higher in the sour fruited varieties.

Diseases Prone:

Bearing Age: 5-10 years from seed; much sooner from grafts and cuttings. Small grafted trees will fruit will attempt to fruit prolifically even in a pot. They flower and fruit continuously 2-5 times a year, with a brief respite in winter.

Fruit: Fruit of 5-6 fins, which when sliced in half width-wise, shows a star pattern. Fruit are often cut into spears, as the seed sheaths are easily removed this way. Cultivated types are sweet, watery, aromatic, and have a refreshing flavor.

History/Origin: Southeast Asia.

Species Observations:

Propogation: Propagation: By seed, cuttings and grafts. Seedling trees are variable in fruit quality. Cuttings produce slightly weaker trees. Grafting is the preferred method with this species.
