Astrophytum myriostigma 'Onzuka' [small] [limited]

Highlights

Astrophytum myriostigma 'Onzuka': A rare collector's cactus with (usually) 5 wide ribs that give it a star-like shape. The small stem is often spineless and heavily speckled with white dots that help it camouflage in its rocky habitat. It blooms in spring/summer with a 3.0" long, shiny yellow flowers. It is a Japanese cultivar with larger, more profuse white speckles than the type species. This slow-growing plant is currently 1.0"-2.0" in diameter and 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.
