  • Uses:  
    This is a nice container plant. It can be grown outside in Southern California and forms spreading flat mounds which are appropriate for cactus, succulent, rock and xeriscape gardens.
  • Propagation:  
    Divide plants and replant pups. Seed – unblemished fruit should be significantly overripe before harvesting seed; clean and dry seeds. After proper cleaning, seed can be successfully stored.
  • Problems:  
    Root and fungal rots in poor draining soils.
  • Special notes:  
    This small, low growing cactus clusters freely and forms flat mounds. Its dark green body is covered in short, flat, white spines, giving the whole mound a whitish appearance. Flowers are lemon-yellow. Mammillaria fragilis breaks apart easily (hence its species name) and forms new colonies wherever pups fall.
