Osteospermum oppositifolium is a rounded shrub of 1 m tall with opposite leaves as the name indicates. The much branched stems are brittle. The leaves are narrow, sometimes toothed and semi-succulent while usually with a grey bloom. The flowerheads have pale yellow to golden ray florets and dark centres that warrant the colloquial name of dark-eyed window-seed. What window-seed signifies is unknown; Osteospermum means bone seed (Manning, 2009; Manning and Goldblatt, 1997).
