I bought a start of this hibiscus from a mail-order nursery whose name I no longer remember. In ten years, it has grown to a tree-like 20' tall and wide. From early spring to mid-fall, it blooms profusely with beautiful red-stamened white hibiscus flowers. Hummingbirds love it. It tolerates drought, has few pests (maybe aphids), but does not like frost. Almost perfect, if a bit large, for my tropicalesque coastal San Diego garden.

There are many different varieties of Hibiscus arnottianus some varieties have larger blossoms some varieties have smaller foliage. All of them have white fragrant flowers the stamens are red and in some species yellow pollen is visible, if not then pollen is red.
The native Hawaiians called this plant koki'o ke'o ke'o
(co key oh kay oh kay oh). Hibiscus arnottianus sometimes hybridizes with Hibiscus waimeae (koki'o kea)
