Osteospermum (African Daisies)
Osteospermum has grow to be a popular plant for mass flower displays in the South African gardens. Growing Osteospermum at home is very easy. The genus name “Osteospermum” is derived from both Greek and Latin and is a direct reference to the appearance of the seeds. In Greek “osteon”, means “bone” and in Latin “spermum”, means “seed”. Osteospermum are native to Southern Africa, for this reason they’re commonly referred to as African Daisies. They flourish in heated, sunny locations and need well-drained soil, in fact, will tolerate very dry sandy soils, making them a perfect alternative to water wise gardens.
Osteospermum used to belong to the genus Dimorphotheca, but only the annual species remain in that genus; the perennials belong to Osteospermum. The genus Osteospermum is also closely related to the small genus Chrysanthemoides, such as C. incana and C. monilifera.
You can count on Osteospermum to begin blooming about mid-end July with a prolific display of flowers that will continue to bloom late into the summer. For this reason they may need a bit more fertilizer. But the great thing about African daisies is that they may be one of the few plants that will bloom for you, even if they're planted in very poor soil.
