Osteospermum ecklonis flowers in a garden. The flower is also known as Cape marguerite, Van Staden's River daisy, Sundays River daisy, white daisy bush, blue-and-white daisy bush, and is native to South Africa.
Plants were brought back to Europe in the late 19th century for cultivation, and today there are a wide range of cultivars available. The plant is named after C.F. Ecklon, who was one of the early botanical explorers of the East Cape, where the flower grows.
