Mammillaria gracilis

Description

One of Sean’s childhood plants, this is a clustering small cactus from central Mexico that eventually produces 8 mounds covered with crystalline white spines and, in summer, pinkish flowers. Any brightly lit situation is fine, especially those that dry out a bit in winter. A good small rock garden plant where temperatures remain above 20F, USDA zone 9.
