Ferocactus pilosus - Mexican Lime Cactus

Mexican Lime Cactus or Mexican Fire Barrel (Ferocactus pilosus) (Werdermann): A large barrel cactus that sports funky, pink spines. This species has 13-20 ribs lined with red to pink spines. In the wild, mature plants can reach up to 10.0' tall and 20.0" in diameter. When grown in hot, sunny conditions, the Lime Cactus can bloom in late winter to spring with vibrant red-orange flowers. These flowers develop into juicy fruit that tastes of lime. It can produce offsets and grow into a large cluster.

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. Keep dry in winter.
