Milo is a culturally important tree likely introduced to the Hawaiian Islands by Polynesian settlers. It can be recognized by its glossy, heart-shaped leaves, yellow, dark-throated hibiscus-like flowers, and woody, brown fruit in the shape of compressed globes. They grow well in low-lying, coastal areas with fruit that float and seeds that germinate on the beach. For this reason, this species is now widely naturalized in tropical coastal areas across the world. The fine-grained wood is valued for carving, and the bark yields tough fibers used for cordage, fishing lines, and coffee bags. Hau (Hibiscus tiliaceus) is an indigenous related member of the cotton family (Malvaceae) with fruit that split open at maturity and leaves lacking the long tips of milo. Thespesia populnea has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of 9 (High Risk), and the Plant Pono link is: https://plantpono.org/pono-plants/thespesia-populnea/.
Native to Worldwide Tropics.
