Stapelia gigantea
From southern Africa, a spineless, four-angled stem succulent that forms clumps and bears very large, carrion-scented star-shaped flowers attracting flies, and is drought-tolerant with tolerance for sun, shade, and varying moisture.
Common Names
Carrion Flower, Zulu Giant, Carrion Plant, Toad Plant, Starfish Flower, Giant Toad Plant
Summary
Originating in southern Africa and Zambia, this spineless, four-angled stem succulent forms clumps up to about 1 m wide and grows about 8–30 cm tall. It bears some of the largest flowers among succulents: star-shaped blooms up to 20–40 cm across, pale yellow to biscuit with maroon lines, fringed with white hairs and a deep central disk. Leaves are absent; stems store water, and a strong carrion odor attracts carrion flies for pollination, giving the plant its notorious scent.
Cultivation prefers full sun to light shade in gritty, well-drained soil; water sparingly, allowing soil to dry between waterings, with a cool, dry rest in winter. Hardiness corresponds to USDA zones 9a–11b; outdoors in frost-free areas, or in containers moved indoors in cooler climates. Propagation is by seeds or stem cuttings. In gardens it can serve as ground cover in xeric/rock gardens, as a focal plant, or in containers and hanging baskets, and pests such as mealybugs and scale may occur.
