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.
