Epithelantha greggii

A tiny, densely white-spined button cactus of the Chihuahuan Desert in Coahuila and Nuevo León, growing in limestone rubble under strong sun. It is slow, rots easily when wet and cool, and does best with very bright light, a mineral mix and a dry, cool winter.

Where it grows wild

Limestone hills and gravelly slopes of the Chihuahuan Desert, usually among rocks or at the base of low shrubs. Conditions are inferred from the measured climate and what is known for the genus.

Measured records sit around 770–1,210 m; only three records carry an elevation, so the true range is probably wider.
