Distinctive low, clumping cactus from central Mexico with cylindrical stems. Relatively common in cultivation. Various named and unnamed cultivars are available, but the most common forms locally have creamy yellow to orange-brown spines and whitish flowers. A version with red spines and flowers also exists. Large mature clumps can be quite striking. The crested form of this plant (so-called brain cactus) can be very impressive in old age.

The two subspecies (echinaria and elongata) occur together in habitat and can be distinguished based on the presence or absence of 2-3 dark central spines (echinaria has them), the width of the stems (echinaria is wider), and the topography they prefer (echinaria's is less vertical).

Easy to start from cuttings. Provide excellent drainage and strong light. Avoid deep pots. These plants thrive in day-long sun here and in habitat.
