Old-Man Cactus Overview
Cephalocereus is a genus of around 12 columnar, clump-forming perennial cacti from the Cactaceae family. These plants are native to arid rocky areas in Central Mexico. They grow on average 5-15m and are usually unbranched and blue-green in colour. Characterised by long white hairs all over the plant surface, this genus is commonly known as Old-Man Cactus, for its resemblance to unkempt grey hair on an elderly gentleman. It produces large red, yellow or white flowers but this can take 10-20 years before a plant reaches flowering maturity.
