This is one of my favorite cacti!
The homeland of the Gymnocalycium is South America.
Gymnocalycium needs a lot of bright light.
But in extreme heat, he needs shading from direct sunlight.
In winter, the best temperature for Gymnocalycium is from +15 to + 18 ° С.
But they can withstand even lower temperatures, up to + 5 ° C.
