Stapelia gigantea, the Carrion Flower or Giant Starfish Flower, is a clumping succulent grown for its spectacular, enormous star-shaped blooms that can span 25 cm or more. The pale yellow, red-lined, wrinkled and hairy flowers emit a strong carrion odour to attract pollinating flies, making them a fascinating curiosity. Native to southern Africa, the plant itself forms upright, soft, four-angled green stems without true leaves. It is drought-tolerant and easy to grow in bright, warm conditions. Best placed outdoors or on a balcony when in bloom due to the scent, it is a prized conversation piece for succulent collectors.
