The name Osteospermum is derived from the Greek osteon (= bone) and Latin spermum (= seed). Osteospermums belong to the daisy family (Asteraceae), hence their common names: African Daisy or South African Daisy, Cape Daisy and Blue-eyed Daisy.
They mustn't be confused with the annual Dimorphotheca. Although most commercial Osteospermum species are labelled as annuals they are in fact half-hardy perennials or subshrubs. This means they are not entirely hardy and will therefore not survive persistent frosts. However, they can be propagated by cuttings or overwintered in a frost free environment.
