It grows on Rich soils in moist, shaded forests, often forming impenetrable thickets when growing in swampy areas and along the sides of streams.

Salak is a very short-stemmed palm tree, with leaves up to 6 metres (20 ft) long; each leaf has a 2-metre long petiole with spines up to 15 centimetres (5.9 in) long, and numerous leaflets. The fruits grow in clusters at the base of the palm, and are also known as snake fruit due to the reddish-brown scaly skin. They are about the size and shape of a ripe fig, with a distinct tip.

Salak fruit is an evergreen, acaulescent, very spiny, tillering, usually dioecious palm growing in clumps formed by successive branching at the stem base. Roots are superficial, not deep and new roots emerge from the stem immediately under the crown, the internodes are short and crowded. They are found growing in humid tropical lowland conditions. Salak is usually grown under partial shade as it grows and performs better than in full sun. Salak is usually cultivated on mineral soils such as well-drained clayey loams, sandy loams and lateritic soils. Stems are subterranean stolon, with a short, 1–2 m high, 10–15 cm diameter, erect aerial part bearing the leaves. Similarly leaves are Pinnatipartite, 3–6 m long. Leaves, leaf-sheaths, petioles and leaflets consist of numerous long, thin, blackish spines. Petioles are very spiny and 2 m long. Leaflet segments are unequal, linear-lanceolate, with narrowed base, concave, apex caudate and acute, and 20–70 cm by 2–7.5 cm. Flowers are paired in axils of scales; male flowers with reddish, tubular corolla and 6 stamens borne on the corolla throat and a tiny pistillode; female flowers with tubular corolla, yellow-green outside and dark red inside, a trilocular ovary with short 3-fid, red style and 6 staminodes borne on the corolla throat.


A plant of the humid, lowland tropics, where it is found at elevations up to 500 metres. It grows best in areas where annual daytime temperatures are within the range 22 – 30°c, but can tolerate 12 – 36°c. It prefers a mean annual rainfall in the range 1,700 – 3,100mm, but tolerates 1,400 – 3,500mm. Requires a deep, rich, moist soil and some shade. Prefers a light-textured soil.

Prefers a pH in the range 5 – 6, tolerating 4.5 – 6.5. The palm starts flowering three to four years after sowing. It can be productive for 50 years or more. The scarce data available suggest that annual yields vary from 5 – 15 t/ha. There are some named varieties. A dioecious plant, requiring both male and female forms to be grown near each other if fruit and seed are required. One male plant is usually adequate to fertilise nine females. There is at least one monoecious variety. ‘Bali’ produces inflorescences with both hermaphrodite and staminate flowers; the latter produce functional pollen. Spacing: 10-12 ft. (3-3.6 m) 12-15 ft. (3.6-4.7 m) 15-20 ft. (4.7-6 m) 20-30 ft. (6-9 m).
