Rebutia marsoneri [large]

Rebutia marsoneri (Werdermann): A neat, miniature species of cactus dotted with lots of small areoles. It grows as green, globose stems with lots of low tubercles that spiral up to a sunken apex. It sprouts short, flexible spines that range from brown to white. R. marsoneri blooms often with numerous large, yellow flowers. It is native to Argentina and reaches only 1.6" tall and 2.0" in diameter at maturity. This plant is 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. Keep dry in winter.
