About California barrel cactus

Ferocactus cylindraceus, also known as the California Barrel Cactus, is a robust and solitary columnar cactus, characterized by its prominent ribs and long, curved, reddish to yellow spines. Its geometric shape and hardiness make it ideal for xeriscape gardens, rockeries, or as a solitary specimen in large pots, adding a sculptural touch to desert landscapes or contemporary garden designs.

Native range

Southwestern United States and northwestern Mexico

Care tips

This species thrives in full sun, requiring at least 6 hours of direct sunlight for optimal growth and healthy flowering. Watering should be sparse, allowing the substrate to dry out completely between waterings, especially in winter when it enters dormancy; overwatering is its main enemy. Use a very well-draining substrate, specific for cacti and succulents, with a good proportion of coarse sand or perlite. Avoid waterlogging and excessive humidity at all costs, as this will quickly lead to root and base rot.
