SelecTree: Tree Detail
Photo Locations: Koko Crater Botanical Garden - Honolulu, HI
This species is native to Hawaiian dryland forests, and should be planted more frequently as an ornamental tree, especially on leeward areas of Hawai'i. It flowers during the summer while leafless, when its beautiful, swollen trunk and striking orange bark are most visible. Lightweight wiliwili wood was traditionally used to make canoe outriggers, fishing floats, and surfboards, and seeds are esteemed for leis. Unfortunately, beginning in 2005, the wiliwili has been seriously impacted by the erythrina gall wasp (Quadrastichus erythrinae), which attacks and curls the leaves. A serious enough infestation can lead to death of the tree. Erythrina sandwicensis has no HPWRA (Hawai'i Pacific Weed Risk Assessment) score.
Native to Hawaii.
