Hibiscus
a plant genus of the family Malvaceae (mallow family), consisting of evergreen or deciduous trees and shrubs and of perennial and annual grasses. There are about 250 species distributed primarily in tropical regions. They are less common in temperate regions. The leaves are mostly palmatilobate, and the flowers are usually large and brightly colored.
Many species of Hibiscus are ornamentals; they are cultivated in greenhouses, indoors, and on open ground. Of the woody species, the best known varieties are the China rose, or the Chinese hibiscus (H. rosa-sinensis), a long-flowering house plant, and the rose of Sharon (H. syriacus), which is cultivated extensively in the Crimea, the Caucasus, and Middle Asia. Of the herbaceous species, the best known are H, × hybridus, a perennial polyhybrid with large flowers, and the flower-of-an-hour (H. trionum), an annual plant with yellow flowers that is found in the southern USSR as a weed. Kenaf (H. cannabinus) is of great economic importance.
