Ferocactus macrodiscus

A low, flattened barrel cactus with pinkish-red spines and purple-pink flowers from the high plateaus of central and southern Mexico. It grows at 1,700–2,700 m with cool, dry winters and summer rain, so it takes more cold than most Ferocactus but needs full sun and a dry winter.
