For many years osteospermum, formerly known as dimorphotheca, was raised annually from seed as a half-hardy annual, and it is still worth sowing some mixtures for choosing good forms to keep going from cuttings. Many named cultivars have been developed since then, and have become popular for summer bedding, especially in containers in warm sunny sites. 'Buttermilk' is an attractive fresh colour, soft creamy yellow, becoming paler towards the centre, which is dark and reddish. Plants flower profusely early and late. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
