Gerbera is a genus of plants in the (daisy family). It was named in honor of German botanist and medical doctor Traugott Gerber. Gerbera is native to tropical regions of South America, Africa and Asia. Gerbera is also commonly known as the African Daisy. Gerbera is very popular and widely used as a decorative garden plant or as cut flowers. The domesticated cultivars are mostly a result of a cross between Gerbera jamesonii and another South African species Gerbera viridifolia. The cross is known as Gerbera hybrida. They vary greatly in shape and size. Colors include white, yellow, orange, red, and pink. The center of the flower is sometimes black. Often the same flower can have petals of several different colors. Gerbera is also important commercially. It is the fifth most used cut flower in the world (after rose, carnation, chrysanthemum, and tulip). It is also used as a model organism in studying flower formation.
