Description: S. gigantea is a stem succulent that resembles a cactus; the branches are velvety, spineless, quadrangular in cross-section and determinate, ceasing growth when about 10 to 30 cm tall, may form big clumps up to1 m in spread.
 
Blooming Time: October. The inflorescence arises near the base of a branch; on this plant the inflorescence had two buds with scale-like leaves at the base of the petioles. When this flower opened., the second bud was aborted. Flowers are extremely large, soft and pulpy to the touch, star-shaped and give off a pestilent smell that attracts flies that ensure the successful pollination of this species.
The flowers have a leathery texture mimic the rotting flesh of a dead animal (like meat and fat rotting in the hot sun) and vary from pale yellow to reddish brown with an elaborate pattern of dark reddish stripes. They remember drying flesh peeling back from the bone and also fringes of soft white hairs on the corolla segments superficially resemble a layer of mold growing on rotting matter.

The large leathery flowers give off a pestilent disgusting smell that attracts pollinating flies.

Culture: Fertilize once during the growing season with a balanced fertilizer diluted to ½ the strength recommended on the label. They need a well-drained potting-mix and can withstand extreme heat but avoid direct sun in summer. Best in partial sun or light shade.
Frost Tolerance: They need a cool, dry rest period in winter but keep above 10°C and avoid any frost.

Propagation: are propagated by stem cuttings. Take cutting in spring when new growth begins. Let cuttings callus up for 2-3 weeks before planting.
