SelecTree: Tree Detail
BREADFRUIT OR ULU
Photo Locations: Oahu, HI, Hanalei and Greenwall Garden, Kona, HI
Breadfruit originated in the Indo-Malay region and was moved to many Pacific Islands by seafaring voyagers. Ulu, the name used by native Hawaiians, is an important Polynesian introduction to Hawai'i. The nutritious fruit and seeds are edible, although most widely grown varieties in Hawai'i are seedless. The trees provide medicine, fabric, construction materials, glue, insect repellent, and animal feed, among other uses. Trees produce the first fruit 4 years after planting and can be productive for decades. Native Hawaiians ate the fruit, fashioned surfboards from its light wood, made tapa from its bark, and used the milky sap to trap birds for their colorful feathers. Artocarpus altilis has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of -12 (Low Risk), and the Plant Pono link is: https://plantpono.org/pono-plants/artocarpus-altilis/
Native to Indo-Malaysia.
