Tephrocactus subterraneus [bare root]

Highlights

Tephrocactus subterraneus (now Maihueniopsis subterranea): Rare collector's cactus. Round, bubbly offsets with robust spines and masive taproots. Its name references the way it grows in the wild with all but the top 0.4" under ground. This is a bare root plant and measures 2"-3" long.

This cactus variety will not survive a hard frost, but if there is a risk of temperatures below 40F, 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.
