Gymnocalycium anisitsii blooms

Today I’m with a cactus. This year, like last year, it pleased me with two flowers. I couldn’t catch the first one in full bloom, but I was lucky with the second one: it opened on Friday.

This species is also known to many as gymnocalycium damsii and under other synonymous names in the nomenclature.

Gymnocalycium anisitsii

Gymnocalycium anisitsii more often grows as a solitary plant and does not particularly strive for vegetative reproduction: even if baby plants are formed on the stem, it takes a decent amount of time. The cactus can reach 8-15 centimeters in diameter and 10 centimeters in height, keeping the overall shape close to flat-spherical.

The species is native to southern Brazil, Paraguay and Bolivia, where the plants occupy open areas in large groups in the shade of low shrubs.

How to grow gymnocalycium anisitsii

Gymnocalycium, like all cacti, is completely undemanding in care. Regular, but not excessive, watering in summer and practically dry wintering are the main conditions. In winter the temperature should not approach 0 °C, although science knows of cases where the plant survived at -5 °C.

Even though you have a cactus in front of you, it is advisable to provide light shade from direct rays at midday. It can withstand bright sun for some time, but this can be fraught with burns.

Also gymnocalycium anisitsii has a relatively quick root system for cacti, so it is better to transplant it once a year or when the roots have fully mastered the volume of the pot. There is no need to keep it in a tight space.
