Longan is occasionally grown in Hawai'i as a dooryard fruit tree and has been recommended for street tree planting. The fruit is produced in late summer and fall. Trees are self-fertile but bear erratically, with heavy fruit production in some years and almost none in others. They require rich soil and regular applications of fertilizer when bearing. Fruit can be used cooked or raw and the flesh of the fruit is used as an antidote for poison. The seeds can be made into shampoo and burnt for fuel. Dimocarpus longan has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of -2 (Low Risk).
Native to Southeast Asia.
