Osteospermum is a genus belonging to the Calenduleae, one of the smaller tribes of the sunflower family (Asteraceae). Osteospermum used to belong to the genus Dimorphotheca, but only the annual species remain in that genus; the perennials belong to Osteospermum.

The scientific name is derived from the Greek osteon (bone) and Latin spermum (seed). It has been given several common names: African Daisy, South African Daisy, Cape Daisy and Blue-eyed Daisy. There are about 50 species, native to Africa, 35 species in southern Africa, and southwestern Arabia. They are half-hardy perennials or subshrubs. Therefore they do not survive outdoor wintry conditions, but there is still a wide range of hardiness.

Most widely sold cultivars are grown as annuals and are mainly hybrids of O. jucundum, O. ecklonis and O. grandiflorum and can be hardy to -2°C. If hardy, they can be grown as perennials or as shrubs. The photo is of a relatively newly introduced cultivar known as "Tradewinds Pure Yellow". They flower repeatedly and produce beautiful waves of colour during the growing season. This is a patented variety that was introduced in 2006 and the flowers are sterile and will not set seed.
