Description
Mammillaria grahamii is a small cactus found underneath or near shade-producing shrubs in the Upland subdivision of the Sonoran Desert at elevations between 2000 and 4500 ft. In good habitat, a single acre may contain thousands of plants. In July, flower buds are produced soon after the humidity increases at the beginning of the Monsoon. The tasty fruit are enjoyed by desert birds and rodents. Compare with Mammillaria heyderi.
