Guide
The species-level account. Cultivar pages build on this and say where they differ.
A small clustering cactus from the arid limestone hills of northeastern Mexico, covered in soft feathery white spines. It stores water in its body and rots if kept damp, so plant it in gritty, fast-draining mix and water only when the soil is bone dry all the way through. Give it the brightest light you have, ideally several hours of direct sun.
