Notes: The 'Gymnocalycium asterias ( or asterium)' synonym was recently deemed an illegitimate name during reclassifications, but it is still widely used.

Cultivation and Propagation: This Gymnocalycium is supposed to be one of the most difficult species in cultivation, and very slow to get to a reasonable size. It will offset after a considerable period of time. It is a summer growing species that needs regular water in summer (but do not over-water ). Keep rather dry in winter. This plant does not like extremely bright situations. Give it some shade during the hottest part of the day. Keep this plant in a low pH compost; otherwise growth will stop altogether. Feed it with a high potassium fertilizer in summer. It is quite frost resistant if kept dry (hardy to -5° C)
.
Propagation: Direct sow after last frost.(seldom produces offsets)
