About

Solanum repandum is a species of evergreen shrub native to various island groups across the Pacific Ocean (Bismarck Archipelago, Cook Islands, Fiji, Mariana islands, Marquesas, Niue, Pitcairn Islands, Samoa, Society Islands, Vanuatu), and occasionally grown for its edible fruit.

Only partially domesticated and very rare in cultivation outside of its native range, it is also known as kokoua or huou. Solanum repandum will apparently hybridize with a number of close relatives, including the South American naranjilla, pseudolulo, and Solanum candidum, along with the Solanum lasiocarpum, from India. Solanum repandum is, in fact, so similar in growth habit and in its fruit that it has been possibly considered a subspecies of either Solanum quitoense (naranjilla) or Solanum lasiocarpum.

Where it grows

Solanum repandum is presumed to be native to a wide areas scattered around the archipelagos of the Pacific. Like the cocona, naranjilla, and Indian nightshade, S. candidium can bear fruit within 1 or 2 years from seed. A short-lived perennial, fruit production requires a rather long growing season, which limits its agricultural potential in more temperate climates, though hybridization and breeding might make this a species worthy of further investigation.
