General Notes

This plant is weedy. We do not recommend planting it in Hawai’i.

This tree, which is native to coastal South America, is naturalized in a number of places throughout the world, including Hawai'i. In Hawai'i, gardeners and foresters no longer plant it, yet it is common in coastal areas on the dry leeward sides of all the major islands. All the individuals in Hawai’i are said to descend from one tree, which was planted in front of the Catholic Mission in downtown Honolulu in 1828. Kiawe’s hard wood makes excellent charcoal and the flowers are a source of nectar for honey. Prosopis pallida has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of 20 (High Risk).
