Yes cactus flowers never get old! IMO they’re the best at making flowers🙂.

The top one I believe is G. mihanovichii cv. Hibotan. These moon cactus aren’t know for living super long.

The second one I’m not sure, but def a Gymnocalycium🌵. There’s one that is known to be very prolific G. multiproliferum, but the spines don’t really match, so idk. I was reading what Cactiguide says about Gymnocalyciums and this is sooo true:

”It is fairly easy to place an unknown cactus into the genus Gymnocalycium especially with a flower bud. Choosing the species is another matter.”
