Hawaii - Island of Oahu
 
HAWAIIAN HIBISCUS
The genus hibiscus adds a great variety of color to the Hawaiian flora. The bright red Hibiscus kokio flowers are descended from the same pioneer ancestor that evolved to become two white-flowered species: H. waimeae from Kaua'i named for Kaua'i’s Waimea Canyon and H. arnottianus found on O'ahu. These two native whites, Koki'o ke'oke'o, are the only hibiscus in the world that give off a faint perfume at dawn and dusk. In the late 1980’s the bright yellow-flowered endemic Hibiscus brackenridgei, Ma'o hau hele, became the state flower. This endangered species survives in the wild in very few places.
