These large, eye-catching, dinner-plate sized hibiscus represent the words “tropical flower” better than any other. Originating in Asia and the Pacific Islands, Hibiscus is the national flower of Malaysia and the state flower of Hawaii. Decades of intense cross breeding with the rosa sinensis species has produced some unbelievable multi-colored blooms. The American Hibiscus Society was formed in 1950 to promote, develop and improve upon the hundreds of varieties that were quickly emerging.
Single vs. Double
There is both single and double flowering tropical hibiscus in the rosa sinensis species. The ‘Fancy’ cultivars have growth habits of both upright and spreading. Within this group, reside two general forms: the brightly colored, usually sold colored single blooms (sometimes double) that propagate easily and are often used as seasonal potted plants as well as tropical landscape shrubs. hese are often sheared to hedges in frost-free landscapes.
