Hibiscus is a diverse genus made up of roughly 220 species of annuals, herbaceous perennials, shrubs, subshrubs, and trees and has been cultivated for cen- turies. The name ‘Hibiscus’ comes from hibiskos, the 32 old Greek name for the common marshmallow. The most commonly grown species is Hibiscus rosa-sinen- sis, which means China Rose. They have large, flat, conspicuous, trumpet-shaped flowers, with five petals, ranging from white to pink, red, purple or yellow. The petals range in size from 1 ½ inches to 6 inches wide. Hibiscus is native to the tropical region of Asia, and tends to grow in wet or swampy areas. Many plants of this family are useful ornamen- tally, while some are also sources of fiber, food, and medicine. Hibiscus tea is caffeine free, with a unique, delicious taste. It is distinctive, vibrant, with a natural color, and is rich in Vitamin C. The flowers are busy members of the mallow family with hundreds of dif- ferent hibiscus species. The flowers are large and brightly colored, shaped like a horn or trumpet, and some species will change color as they age. The most popular and conspicuous use for the flowers is deco- rative, with other uses being for cooking in herbal teas, and for garnishing. Besides being used for orna- mental purposes, some hibiscus varieties have specific uses ranging from industrial uses to medicinal uses. GG www.GardenandGreenhouse.net May 2019
