Hardiness: Plants are and quite frost hardy -5 (-15)° C but preferably overwinter in a cool place (at 0/10°C). They need to be kept in a cool place during winter rest. This is important for the flowers, as well as for their health. Without this cool winter period, they normally won’t get many buds.

Watering should be done carefully, allowing the plant to almost dry out between waterings. The cactus mustn’t be exposed to prolonged dampness and sitting water. Never let your cactus sit in a dish of water. For the best viewing, instead of propagating your offsets, let the plant for a large cluster.
