Glue berry (Cordia dichotoma) is a small to medium tropical tree grown across Asia and the Pacific for its sticky edible fruit, its fodder, its useful wood, and a long tradition of herbal use.1 Also called clammy cherry or Indian cherry, it is native to a wide swathe of warm Asia and northern Australia and turns up readily in village lands, hedgerows, and forest edges, which makes it a forgiving multipurpose tree for a homestead on hot, seasonally dry ground.1 The common name comes straight from the fruit: the ripe pulp is translucent and mucilaginous, sticky enough to have served as a natural glue.1
It is a deciduous tree, typically 3 to 15 m tall, with a short bole and a spreading crown.1 The leaves are simple and alternate, broadly ovate to elliptic, 6 to 20 cm long, with entire or slightly wavy margins and a distinctly clammy, sticky feel when young thanks to the plant’s mucilage.1 The bark is grey to brown, fairly smooth on young wood and becoming shallowly fissured with age.1 Small, white to greenish-white, funnel-shaped flowers, about 1 to 1.5 cm across and mildly fragrant, are carried in short axillary clusters near the branch ends, usually blooming in late spring to summer.1
Growing glue berry
Glue berry is a tropical to subtropical tree. In the wild it grows from sea level up into lower montane zones, ranging across dry deciduous forests, moister deciduous forests, and even tidal or coastal forest, and it readily colonises village lands, hedgerows, forest edges, and degraded sites — a pattern that points to good tolerance of heat and seasonal drought.1 Its native range spans southern China, the Ryukyu Islands of Japan, Taiwan, the Indian subcontinent and Sri Lanka, mainland Southeast Asia, the Philippines, Indonesia, Malaysia and New Guinea, and the Northern Territory and Queensland of Australia.12 It has been introduced to parts of the Caribbean, Central America, Florida, and Mexico.1
Primary floristic sources do not assign this tree a USDA hardiness zone. Its distribution through frost-free and only lightly frosted lowland tropics and subtropics suggests it behaves like other tender, warm-climate trees — roughly USDA zones 10 to 11, perhaps 9b where frost is light. Treat that as a climate-matching inference, not a documented figure: the tree wants warmth and dislikes hard freezes.1
Glue berry is commonly grown from seed, the standard route in forestry and agroforestry plantings.1 To prepare seed, the mucilaginous pulp is cleaned off to free the hard stone (the stony endocarp) holding the seed.1 Detailed cultivation figures — sowing dates, spacing, irrigation, and time to maturity — are not consistently documented in the general sources here, so they are left out rather than stated with false precision. In practice, site it in full exposure on free-draining ground, water young trees to establish them, and expect it to handle heat and a long dry season once settled.1
Harvest and uses
The fruit is a nearly globose drupe, typically 1 to 2 cm in diameter, that starts green, turns a shining yellow or pinkish-yellow as it ripens, and finally goes black when fully ripe or dried.13 Inside the sticky, translucent pulp sits a single hard seed enclosed in a stony endocarp.1 The shining yellow-to-black drupes, the mucilaginous pulp, the small white flowers, and the clammy young foliage together make the tree distinctive across tropical and subtropical Asia and northern Australia.12
Both the ripe fruit pulp and the unripe fruit are eaten — the ripe pulp fresh, and the green fruit pickled — and the same tree is widely used for fodder, for materials, and in traditional medicine across Asia and the Pacific.1 Its mucilaginous pulp doubles as a natural adhesive, the origin of the “glue berry” name.1 For a homesteader the appeal is breadth: a single hardy tree on rough ground that yields a pickling and dessert fruit, browse, and useful wood.
Safety and cautions
The ripe fruit pulp and pickled unripe fruit of glue berry are widely eaten, so the fruit itself is a food in its own right.1 However, the sources are explicit that the tree also has strong laxative and other pharmacological effects, which means medicinal use of its parts is a different matter from eating the fruit.1
Because of those effects, any medicinal use should be approached with caution and professional supervision rather than self-administered, and this profile makes no claim that the plant treats or cures any condition.1 Traditional use across Asia and the Pacific is well documented, but a long history of use is not the same as proven safety or efficacy.1 Stick to the fruit as food, treat the rest of the plant as a potent herbal material, and seek qualified guidance before any medicinal use — particularly if you are pregnant, breastfeeding, or taking medication.
