Hibiscus tiliaceus, commonly known as the sea hibiscus or coast cottonwood, is a species of flowering tree in the mallow family, Malvaceae, with a pantropical distribution along coastlines. It has also been introduced to Florida and New Zealand. It has been debated whether this species is native or introduced to Hawaii. [1]

Hau cordage (ʻili hau) is made from the inner bark while flowers are used for laxative properties. Hau is seen as the visible form of Mānoa wind. The tree is sacred, its legendary genealogy leading directly back to the great gods of Polynesia.

Small evergreen native tree 13–33 ft (4–10 m) high, with short crooked trunk to 6 inches (15 cm) in diameter and with broad crown of widely spreading or crooked branches, or a shrub with many prostrate branches form-ing dense thickets. Bark gray or light brown, smooth; inner bark fibrous.

Early Hawaiians used the wood of this species to build the outriggers of canoes, floats for fish nets, long spears for games, and for the cross sticks of kites. The fibrous inner bark of the Hau was also used to create ropes, matts, and bark cloth.
