Star Fruit, Carambola
Scientific Name: Averrhoa carambola L.
Family: Oxalidaceae
Star Fruit, Carambola (Averrhoa  carambola) Recommended Temperature Zone:
USDA: 10-12

Frost Tolerance: Damaged at 30F (-1C), killed at 26F (-3C)

Sun Exposure: Full sun, slow growing in light shade.

Origin: Indochina

Growth Habits: Evergreen tree, up to 35 feet tall (10 m)

Watering Needs: Regular water

Propagation: Seeds, layering

The Carambola, native to Indochina, is an attractive ornamental tree that attains a height of 30 to 35 feet. The odd-pinnately compound leaves have 3 to 11 leaflets, which are ovate or ovate-lanceolate.

Blooming Habits:
The small, fragrant, rose-colored flowers are produced in cymes from the leaf axils or laterally on the stems.

Fruiting Habits:
The ovoid to ellipsoid yellow fruits are 4 to 5 inches in length and are acutely 5-angled. The fruits are star-shaped when cut across and are crisp, juicy, and aromatic, although usually acid in taste. One form is called the "sweet carambola" because it lacks the acid taste. The fruits have been reported to contain 50 percent of reducing sugars on a dry-weight basis and to be a good source of vitamins A and C. The ripe fruits are used for preserves, jams, and jellies. The star-shaped cross sections make an attractive addition to salads.

The carambola can be grown successfully on soils ranging from sands to heavy clays and is reported to be drought resistant after it has become well established. Propagation can be accomplished readily with seeds, and budding also has been successfully used.
