First flowering of Gymnocalycium riojense subsp. kozelskyanum

This year, one of the most beloved cacti in the collection finally bloomed.

The cactus was bought at a show about 15 years ago, somewhere between 1999 and 2002. I was in middle or high school then, representatives of this species were among the first in my collection. I bought two so I could then pollinate and get my own seeds, though it made more sense to set such Napoleonic goals with violets or something else fast-growing. Fortunately, both are still alive, and I finally waited for the first flower. They were at least 2 years old at the time of purchase (I remember roughly what they looked like then).

If you are interested in the size he has grown to by now, here are: about 5 cm in diameter and 2.5 cm in height. The approximate age is at least 16-17 years old. The diameter of the flower is 4 cm.

By the way, the name of the species at the time of purchase was listed as Gymnocalycium kozelskyanum. Only recently I found out that this is one of the four subspecies of Gymnocalycium riojense, identified in 1991. In the natural environment it is found in Argentina in the provinces of Catamarca and La Rioja at an altitude of 0.5-1.5 km above sea level.
