I thought I knew what these were but suddenly am having second thoughts after all these years. I thought they were all Gymnocalycium but (Oh-oh!), they all have fuzzy buds. I don't recall Gymnos having fuzzy buds. Any thoughts?
I think the yellow one and the apricot one are both Parodia. Maybe P. herteri (apricot) and P. mammulosus (yellow) or both P mammulosus?
Pink one, still not a clue but thinking....
Thanks Drawling. I'm pretty sure the pink one and the apricot one are Parodia but I don't think we have the same ones. I used to buy any Notocactus I saw because they always have outstanding flowers.
Looking at the spines on yours, I wonder if the Pink one is also a Notocactus/parodia.
