osteosperma

Osteosperma is a genus of flowering plants in the family Asteraceae, commonly known as osteospermums or cape daisies. These plants are native to southern Africa and are widely cultivated as ornamental plants for their colorful and daisy-like flowers. The genus Osteospermum comprises several species, with Osteospermum eximum being one of the most popular and widely recognized.

Osteospermums are typically herbaceous or shrubby perennials, though some are grown as annuals. They are characterized by their vibrant flower heads, which come in a variety of colors including white, yellow, orange, pink, purple, and red. The flowers often have a distinct central disc, which can be a contrasting color to the ray florets. The leaves are usually ovate or lanceolate, and can be entire or toothed. They are generally hardy plants that prefer full sun and well-drained soil.

The name Osteospermum is derived from the Greek words "osteon" meaning bone and "sperma" meaning seed, referring to the hard, bone-like nature of their achenes. These plants are propagated by seed or cuttings and are popular in gardens, containers, and as cut flowers. They are relatively low-maintenance, requiring regular watering and occasional deadheading to encourage continuous blooming. Osteospermums are a common sight in many temperate gardens worldwide.
