Family: Lecythidaceae

Barringtonia edulis, commonly known as cut nut, is a medium-sized tropical tree native to Melanesia. It is grown for its large, nutritious nuts, which can be eaten cooked or roasted, and for its attractive appearance in landscaping. The tree has glossy leaves, showy pink-white flowers, and a sturdy form that makes it popular in home gardens throughout the Pacific. It prefers warm, moist climates and can tolerate coastal conditions, including salt spray.

In Hawaiʻi, cut nut is not known to be invasive, and there is currently no evidence of naturalizing in local ecosystems. While it produces sizable fruits, they are relatively heavy and not easily dispersed long distances. This reduces its potential to spread on its own. As with any introduced species, however, gardeners should plant responsibly, monitor for unwanted seedlings, and dispose of plant waste properly. For those seeking an edible and visually appealing tree with low invasive risk, cut nut can be a suitable choice.
