White Kauai Hibiscus
Evergreen, Shrubs, Trees
Big, brilliant flowers on plump shrubs rank this among the showiest flowering shrubs in Western gardens. Some are very tender tropical species grown in Hawaii, others very hardy. Plants typically bear funnel-shaped blossoms, often with prominent stamens.
Giant whitefly is the most important pest of hibiscus in central and Southern California, coating the undersides of leaves with wax and eventually defoliating the plant. A parasitoid wasp has been released to control it, and research continues on its control.Hibiscus waimeae
