Starfish Flower plants resemble cacti, with clumps of four sided, spineless stems. Summer flowers are large, fleshy, shaped like five pointed stars; they usually have elaborate circular fleshy disc in center. Most smell like carrion, but odor is not usually pervasive enough to be offensive.
They need cool, dry rest period in winter. Best managed in pots. Good desert succulent, tolerating extreme heat. Protect plants in areas where frost can occur.
