Arctotis venusta is a species of South African plants in the daisy family. Common names include silver arctotis, kusgousblom, and blue-eyed African daisy. It is native to the western coast of South Africa,[1] The species is widely cultivated as an ornamental, and has become naturalized in parts of the United States (California, Arizona, South Carolina),[2][3] Australia,[4] and Central and South America,[5] where it has escaped from gardens to become a noxious weed. [6]

Arctotis venusta is grown as a ground cover because of its silvery foliage and showy flower heads. It is adaptable to many conditions and is sometimes used to control erosion. It is a perennial with stout, woolly stems and aromatic, violin-shaped, heavily lobed leaves. The flower heads have many creamy-white to pink or bronze ray florets with lavender to reddish undersides and centers filled with purple disc florets. The fruit is a hard achene with a tuft of plumelike hairs on one end and an array of pappus scales on the other.[7]

The species is sometimes regarded as the same species as the rare A. stoechadifolia, but authors separate the two as distinct species.[7][2][6]
