Orange Hawaiian Hibiscus In Sunset Stock Image

this is an endemic species of hibiscus with white flowers. Three subspecies are recognized: H. arnottianus ssp. arnottianus found in the Waianae Range of western Oahu H. a. ssp. immaculatus which is very rare on Molokai and H. a. ssp. punaluuensis from the Koʻolau Range on Oahu. Perhaps only a dozen plants of H. a. ssp. 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.
