Design with this plant

Overview

Cephalocereus senilis, commonly known as the Old Man Cactus, boasts striking white, hair-like spines enveloping its columnar body, providing a unique, shaggy appearance. This slow-growing Mexican native can reach up to 15 feet tall but remains slender at 1.5 feet wide. It prefers full sun and well-drained soil. Drought-tolerant and low-maintenance, it adds a touch of whimsy to arid landscapes. Frost-sensitive, ideal in USDA zones 9-11.
