Stapelia gigantea is a species of flowering plant in the genus Stapelia of the family Apocynaceae. Common names include Zulu giant, carrion plant and toad plant (although the nickname "carrion plant" can also refer to Stapelia grandiflora). The plant is native to the desert regions of South Africa to Tanzania.
Growing up to 20 cm (8 in) tall, it is a clump-forming succulent with erect green stems 3 cm (1.2 in) thick. The blooms are large star-shaped five-petalled flowers up to 25 cm (9.8 in) in diameter. The flowers are red and yellow, wrinkled, with a silky texture and fringed with hairs, that can be as long as 8 mm (0.3 in). They bloom in autumn, triggered by the shorter daylight hours.
The flowers have the smell of rotting flesh, in order to attract the flies which pollinate them. [...] There have been several proposed reasons for the size of the flowers of S. gigantea. First, it is possible that they are large to attract the flies that pollinate them. The large size and color of the flowers combined with the carrion smell may cause the flies to behave as if it is a dead carcass and be more likely to visit it
