Mammillaria sempervivi

Highlights

Mammillaria sempervivi (de Candolle): A flattened, globose cactus with a bumpy, spiky look. The stem is an olive green and covered with pyramidal bumps or "tubercles". White wool fills the spaces between the tubercles. It blooms with a crown of white to cream flowers atop its stem. This species is native to Mexico where it stays under 4.0" in diameter. This plant is fully rooted in a 3.25" 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.
