Terminalia catappa is the accepted species commonly called Indian almond, sea-almond, West Indian-almond, or tropical almond. Its native range extends across tropical and subtropical Asia, the Pacific, northern Australia, Madagascar, and the Comoros.^[1] GBIF places it in Combretaceae and accepts the species-level name with an exact match.^[2]

Description

This is a fast-growing coastal tree of beaches, river mouths, and coastal plains. It commonly reaches about 15 m, with larger trees recorded, and develops a broad, spreading habit suited to open tropical landscapes.^[3] The flowers are inconspicuous but fragrant, while the fruit contains a woody endocarp enclosing the almond-flavoured seed.^[3]

Cultivation

Soil and water

In its coastal habitat, Terminalia catappa grows in moderately fertile, well-drained soils and shows a preference for sands and loamy sands. A soil reaction around pH 5–7 is reported, with tolerance of a broader range, and established trees tolerate saline soils, salt spray, and periods of drought.^[3] Drainage remains important: salt and drought tolerance in an established tree should not be treated as permission to keep a newly planted tree dry. Water young trees through establishment, then adjust irrigation to rainfall, soil drainage, and the tree's seasonal leaf response.

Sun and humidity

Full sun suits the open coastal habit. The commonly described cultivation range is the lowland tropics below about 800 m, with mean annual temperatures commonly around 21–32 °C and annual rainfall around 1,500–3,400 mm; the same account gives a broader temperature tolerance of roughly 10–36 °C.^[3] These broad figures are environmental context rather than a guaranteed hardiness range. Give the tree strong light, free air movement, and enough atmospheric moisture or irrigation to prevent establishment stress, especially outside humid lowland conditions.

Seasonal changes

The tree can shed its leaves suddenly, commonly twice a year, rather than keeping an unchanging canopy.^[3] A refoliage sequence can occur as a local seasonal response, but the timing should not be imposed as a fixed calendar: temperature, rainfall, and site exposure alter the rhythm. Reduce irrigation only when the root zone and local season justify it; do not confuse seasonal leaf loss with drought death.

Propagation

Use ripe seed for a straightforward seed-starting trial. A 24-hour cold-water soak preceded about 70% germination in roughly 20 days in one cultivation account.^[3] Treat that result as a practical benchmark rather than a guarantee: seed freshness and storage history can change emergence. The seed is also dispersed by water, consistent with the species' coastal ecology.^[3]

Flowering, fruiting, and harvest

Flowers are inconspicuous and fragrant, and fruit development follows flowering, but a reliable species-wide flowering calendar or bearing age is not supplied here.^[3] In cultivation, observe the tree's local leaf and flowering rhythm rather than applying a calendar from another climate. Harvest only fully developed fruit, removing the fleshy outer portion to reach the woody endocarp and kernel.

Fruit and uses

The almond-flavoured seed is described as edible raw or cooked.^[3] This use concerns the kernel inside the woody endocarp; it should not be read as a food-safety or toxicity claim about every part of the fruit. The species is also selected in cultivation for trees producing larger seeds.^[3]
