Used exclusively in Phoenix as a winter bedding plant for flower borders close to the human eye. Transvaal daisy is popular throughout the world as a bedding plant, decorative pot plant, or cut flower. The genus Gerbera consists of about 30 species which are found in Africa, Madagascar, tropical Asia and South America.
More historical notes: The genus name Gerbera is in honour of the German naturalist Traugott Gerber, and the species was named after Robert Jameson who collected live specimens while on a prospecting expedition to the Barberton district in 1884, even though the species had been collected on three earlier occasions by other people. In 1888, Medley Wood, the curator of the Durban Botanical Garden sent plants to Kew, which subsequently flowered. The breeding of Gerbera started at the end of the 19th century in Cambridge, England, when Richard Lynch crossed G.jamesonii and G.viridifolia. Most of the current commercially grown varieties originate from this cross.
