Hibiscus waimeae (white Kauai rosemallow, Hawaiian: kokiʻo keʻokeʻo, or kokiʻo kea) is a species of flowering plant in the okra family, Malvaceae, that is endemic to the island of Kauaʻi in Hawaii.[1] It is a small gray-barked tree, reaching a height of 6–10 metres (20–33 ft)[3] and a trunk diameter of 0.3 m (0.98 ft).[4] The flowers last for a single day, starting out white and fading to pink in the afternoon.[5] H. arnottianus of Oʻahu and Molokaʻi and H. waimeae are the only Hawaiian hibiscuses that have white flowers.[6] H. waimeae inhabits coastal mesic, mixed mesic, and wet forests at elevations of 250–1,200 m (820–3,940 ft).[1]

H. waimeae subsp. waimeae can be found in the western and southwestern parts of the island, where it grows in the Waimea Canyon area and valleys that face the ocean.[7] H. waimeae subsp. hannerae is rarer (listed as endangered by the USFWS) and can be found in the northwestern part of the island[8] where it grows in the Hanakapiʻai, Limahuli, and Kalihi Wai valleys.[2]
