The species is native to the Fiji Islands and Vanuatu where it grows along the coasts in the humid tropical forests up to about 400 m of altitude.

The genus is honoured to the English lawyer and naturalist Daines Barrington (1727-1800); the name of the species is the Latin term “edulis” = edible, eatable, with reference to the seeds.

Particularly ornamental species due to its great and glossy leaves and the long and showy inflorescences, cultivable exclusively in the tropical and humid subtropical climate zones in full sun or slight shade, especially when young, on soils rich of organic substance kept humid.

In its origin places it is often found planted in the villages around the houses and along the roads and the paths.

The seeds, the edible part of the fruits, of pleasant taste, are consumed raw, boiled or roasted; bark and leaves are utilized in the traditional medicine for various pathologies.

The wood is light, of a density of about 480 kg/m3, and is employed in the constructions, for coverings, paddles, tools and everyday objects and also, locally, as fuel.
