Mammillaria fraileana

Mammillaria fraileana (Boedeker): Clustering, cylindrical cactus. The green stems are covered with bumpy tubercles that sprout white to dark brown spines. It produces large blooms striped pink and white in a ring that crowns each stem. This species is native to Baja California Sur, Mexico.

This cactus variety will not survive a hard frost, but if there is a risk of freezing temperatures it can be brought indoors to grow on a sunny window sill or under a grow light. Cactus need bright sunlight, great drainage, and infrequent water to prevent rot. Pick containers with drainage holes and use well-draining cactus and succulent soil with 70% to 80% mineral grit such as coarse sand, pumice, or perlite. Water deeply and wait for the soil to completely dry out before watering again.
