Some plants you just never expect to flower and this is one of them for me. Surprise surprise.
I have had this cactus for years (I had it IDed while ago but lost the tag again).
If anyone knows the name I'll try again on retaining the name.
Mine bloomed for the first time last year. I believe it is Parodia leninghausii https://en.wikipedia.org/wiki/Parodia_leninghausii
When that one hatched, it was a Notocactus. (Yes, I'm old!).
Yeah, me too. Looking good. The plant looks like it has a few years under its belt. They are amazing once they start clumping like that. Mine flowered in the spring.
We won't ask if you labeled it Notocactus or Parodia as that would give away your age. 8')
I've got plenty of age but my labeling was based on what was given to me here.
