Osteospermum Inflorescence

Osteospermum L.

The inflorescence of Osteospermum is a capitulum with a diameter of 4 to 10 cm, the parameters of which are key characteristics for DUS testing.

In the reference 24 varieties crop Osteospermum, where this is mentioned in the description.

During variety testing of Osteospermum, the diameter of the inflorescence, the shape of the ray florets, and the color of both the ray and disc florets are evaluated. The contrast between the center and the petals is an important breeding trait. A distinctive biological feature of Osteospermum, which differentiates it from most other Asteraceae, is that seeds are formed in the ray florets rather than in the central disc florets.

Inflorescence development is sensitive to photoperiod and temperature regimes, with specific cooling conditions often required to initiate flowering. The plant's branching pattern is directly related to the structure and number of capitula, which determines the overall bush shape and the ornamental value of the variety in landscape design.
