SelecTree: Tree Detail

This plant is weedy. We do not recommend planting it in Hawai’i.
Haole koa is the most abundant naturalized tree in low elevation areas of the Hawaiian Islands. It was once used to regenerate barren, eroded lands, but grew too well and spread over large areas, outcompeting native vegetation. The wood can be used for fire and charcoal and the plant is eaten by cattle and goats, but can be toxic at high levels, especially for horses. Leucaena leucocephala has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of 15 (High Risk).
Native to Southern Mexico, Northern Central America.
