Gymnocalycium stenopleurum

Highlights

Gymnocalycium stenopleurum (Ritter): A deep purple to nearly black, ribbed cactus with contrasting white areoles. The twisted spines are few and of an ash grey color. It blooms with large, white to pale pink flowers from its apex. It grows slowly and can reach about 4.5" in height and diameter at maturity. This plant is small, but fully rooted in a 3.5" 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.
