This subspecies is native to Brazil and stays under 6.0″ tall. Keep it in direct sun to induce violet flushing of its stem. It blooms by sending up a sweet, pink, funnelform flower. This plant is fully rooted in a 3.0″ pot.
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.
