This is one of the most showy succulent plants, an eye stopper. These cacti are natives of southern Arizona and Mexico. They form tall, columnar stems, which branch at the base to form a short trunk. L. schottii var. monstrose is a naturally occurring mutation, which, although sterile, continues to survive in the wild. When a stem breaks off or falls over, it roots along the sides. This mutation has variable, irregularly shaped, knobby-looking ribs with no spines only a few bristles. Its flowers are pink. These slow-growing cacti are suitable for growing as landscape plants, in greenhouses, outdoor containers, and in a window garden. Makes a great addition to any reptile habitat.
