Hawaiian Hibiscus - Native Species

Native Species

The native hibiscus (genus Hibiscus) found in Hawaiʻi are:

• Hibiscus arnottianus – kokiʻo keʻokeʻo ("kokiʻo that is white like the shine of silver") is an endemic species of hibiscus with white flowers. Three subspecies are recognized: H. arnottianus arnottianus found in the Waiʻanae Range of western Oʻahu; H. a. immaculatus which is very rare (listed as endangered) on Molokaʻi; and H. a. punaluuensis from the Koʻolau Range on Oʻahu. Perhaps only a dozen plants of H. a. immaculatus exist in nature in mesic and wet forests. This species is closely related to H. waimeae, and the two are among the very few members of the genus with fragrant flowers. It is sometimes planted as an ornamental or crossed with H. rosa-sinensis. In the Hawaiian language, the white hibiscus is known as the pua aloalo.
• Hibiscus brackenridgei – maʻo hau hele ("hau most similar to maʻo") is a tall shrub (up to 10 m/33 ft) with bright yellow flowers, closely related to the widespread H. divaricatus. Two subspecies are recognized: H. b. brackenridgei, a sprawling shrub to an erect tree found in dry forests and low shrublands at elevations of 400–2,600 ft (120–790 m) above sea level on Molokaʻi, Lānaʻi, Maui, and Hawaiʻi; and H. b. mokuleianus, a tree from dry habitats on Kauaʻi and the Waiʻanae Range on Oʻahu. This species is listed as an endangered species by the USFWS. The yellow flower of this species was made the official state flower of Hawaiʻi on 6 June 1988, and although endangered in its natural habitats, has become a moderately popular ornamental in Hawaiian yards.
• Hibiscus clayi is an endemic shrub or small tree with bright red flowers, generally similar to H. kokio, and found in nature on Kauaʻi in dry forests. It is listed as endangered by USFWS.
• Hibiscus furcellatus is a pink-flowered hibiscus considered an indigenous species, typically found in low and marshy areas of the Caribbean, Florida, Central and South America, and Hawaiʻi, where it is known as ʻakiohala, ʻakiahala, hau hele, and hau hele wai ("entirely puce hau").
• Hibiscus kokio, kokiʻo or kokiʻo ʻula ("red kokiʻo") is a shrub or small tree (3–7 m/9.8–23 ft) with red to orangish (or rarely yellow) flowers. This endemic species is not officially listed, but considered rare in nature. Two subspecies are recognized: H. kokio kokio found in dry to wet forests on Kauaʻi, Oʻahu, Maui, and possibly Hawaiʻi at elevations of 70–800 m (230–2,600 ft); and H. k. saintjohnianus from northwestern Kauaʻi at elevations of 150–890 m (490–2,920 ft).
• Hibiscus tiliaceus, hau, is a spreading shrub or tree common to the tropics and subtropics, especially in coastal areas. This species is possibly indigenous to Hawaiʻi, but may have been introduced by the early Polynesians.
• Hibiscus waimeae, kokiʻo keʻokeʻo or kokiʻo kea ("kokiʻo that is white as snow"), is a Hawaiian endemic, gray-barked tree, 6–10 m (20–33 ft) tall, with white flowers that fade to pink in the afternoon. Two subspecies are recognized: H. waimeae hannerae (rare and listed as endangered) found in northwestern valleys of Kauaʻi, and H. w. waimeae occurring in the Waimea Canyon and some western to southern valleys on Kauaʻi. This species closely resembles H. arnottianus in a number of characteristics.

• Hibiscus arnottianus

• Hibiscus clayi

• Hibiscus kokio
