OLD MAN CACTUS

Cephalocereus senilis

This curious looking cactus is a true oddity in any landscape, and is sure to attract attention for its uniqueness. The modified thorns of Old Man's Cactus give it a dense, hairy appearance that lessens with age. Plant in full sun to achieve the "hairiest" appearance; hair production is an adaptation to high light intensities.
