This fast-growing cactus makes a strong, vertical statement wherever it resides and is often a focal point of the landscape. Its long, low-branching canes grow straight and upright to 12 feet tall, sometimes even taller in frost-free areas. Each cane has 5-7 ribs that feature a tidy row of small spines along a white “stripe” that give this giant succulent a sleek, architectural appearance. Small reddish or pink flowers appear amongst the rows of spines in springtime.
Often used as a living fence or visual screen, this cactus makes a bold statement against a solid wall, but it also stands out on its own as a space-defining border or a large scale accent. Propagation of Mexican fencepost is extremely easy by cuttings or seeds, and even though it’s a top choice for xeric gardens, it tolerates moderate watering if excellent drainage is provided.
