Osteospermum the daisybushes is a genus of flowering plants belonging to the Calenduleae, one of the smaller tribes of the sunflower/daisy family Asteraceae. There are about 50 species, native to Africa, 35 species in southern Africa, and the southwestern Arabian Peninsula. They are half-hardy perennials or sub-shrubs. Therefore they do not survive outdoor wintry conditions, but there is still a wide range of hardiness.
Osteospermum are popular in cultivation, where they are frequently used in summer bedding schemes in parks and gardens. Numerous hybrids and cultivars have been grown with a wide range of tropical colors. Yellow cultivars tend to have a yellow center (sometimes off-white). Plants prefer a warm and sunny position and rich soil, although they tolerate poor soil, salt or drought well.
Modern cultivars flower continuously when watered and fertilised well, and dead-heading is not necessary, because they do not set seed easily. If planted in a container, soil should be prevented from drying out completely. If they do, the plants will go into "sleep mode" and survive the period of drought, but they will abort their flower buds and not easily come back into flower. Moreover, roots are relatively susceptible to rotting if watered too profusely after the dry period.
