Gymnocalycium, commonly called chin cactus, is a genus of about 70 South American species of cactus. The genus name Gymnocalycium (from Greek, "naked calyx") refers to the flower buds bearing no hair or spines.

Their main area of distribution is Argentina, part of Uruguay, Paraguay, southern Bolivia and part of Brazil. Most species are rather small varying from 4 to 15 centimetres in size. In cultivation they are popular for their easy flowering habits, and the flowers are generally brightly coloured. Where temperatures fall below 10 °C (50 °F) they must be cultivated under glass with heat.

These cacti are more popular than you would expect! Did you ever hear about the Moon cacti? They are a superb grafted specimen between two adorable cacti that melted many gardeners’ hearts. And guess what! The top cactus is a Gymnocalycium Mihanovichii, a chubby and colorful companion that gives mild headaches to their owners. But all cacti deserve attention and we are here to support and love them unconditionally!
