Botanical Profile

Culture & Fruit

Native to Southeast Asia (Malaysia, Indonesia), this evergreen tree reaches 20–30 feet. The leaves are compound, sensitive (fold at night). Small, pink-lavender flowers appear in clusters on woody branches. The fruit is 3–6 inches long, crisp, juicy, sweet-tart (flavor varies by cultivar), rich in vitamin C.

It requires tropical conditions: full sun, well-drained soil, high humidity, consistent warmth. Hardy only to 27°F (-3°C) briefly; zones 10–11. In containers, it can fruit at 3–4 feet. The star-shaped slices are beautiful in salads, drinks, and garnishes. A unique, ornamental fruit tree for true tropical climates.
