Coastal and Tropical South
The hibiscus family of tropical and subtropical plants is well documented on this Malvaceae Info site operated by Stewart Robert Hinsley of the UK. This kind of site is often a labor of love (as you can read in the section about its origins and philosophy), and offers a handy way to check the names of plants. Getting info about them is as simple as clicking on the picture.
When Barbara Perry Lawton takes on a plant, you can bet she'll dig deep so you'll learn more than you thought possible about the family's members, history, and cultivation. If you're a fan of hibiscus flowers, there's plenty of eye candy and inspiration in her book Hibiscus: Hardy and Tropical Plants for the Garden, (Timber Press, 2004; $27.95). If you just find them interesting, or have ever had problems with yours that no one could solve, Barbara will enlighten you with the romance of these grand blooms.
Who knew hibiscus flowers were considered lusty by the ancient Egyptians, or that they are associated with the zodiac sign of Aquarius? This book sets the bar high for single species books, and will become a standard for hibiscus afficionados worldwide.
