The group of succulents known as Stapelias originate in southern and southwest Africa. They belong to the milkweed family, Asclepiadaceae. The star-shaped flowers are most unusual and attractive, and in some varieties are sweetly scented. However, the flowers of Stapelia variegata have an unpleasant, although not overpowering, odour. The odour is similar to that of rotting meat, and attracts the blowflies which pollinate the flower.
