RED SILK COTTON TREE
Photo Locations: Foster Botanical Garden - Honolulu, HI
This large, deciduous tree often has prickles on the trunk and main branches when young that become less prominent as the tree matures. The leaves can be harvested as a curry vegetable, the trunks were hollowed out to make canoes, and gum from the inner bark was used in traditional medicine. The soft wood is used for matches and tea boxes, the inner bark provides fiber for cordage, and the silky fruit hair stuffing for mattresses and pillows.
