Well, to be more specific, the yellow hibiscus is the state flower of Hawaii and has been since June 6, 1988. The above photograph is one of a pink hibiscus (rosa sinensis). Tropical hibiscus originated in Asia and the Pacific Islands, and happens to be the national flower of Malaysia.
Tropical hibiscus shrubs are very easy to grow as they prefer the sun and enjoy warmer temperatures. In fact, you can practically see them growing in every other yard on a block.
