Something is wrong with Houzz. Again. I first noticed this post an hour ago and it says it was posted 9 hrs ago.

Looks like P. magnifica too me, but there’s always P. warasii to compare with. When they’re small like this they much look the same, but bigger they look different. Llifle says magnifica is more blue and warasii is more green, and I can’t tell but yours does look more green. But P. warasii has 15-16 ribs, while magnifica has between 11-15. From your pic the only cactus I’m able to count the ribs on has 13 so that would fit with magnifica.

It’s really cool how it’s clumped.

It is very lightly blue-green. I will have to check the other characteristics. The nursery had a number of theses plants, from singles of a nice size on up to this one, a clump. I really liked the clump.

I bet it will get more glaucous as it ages. I’m curious how it will grow as it ages also. Never seperate this guy because it looks so nice as is. Usually I don’t like when a cactus pup like crazy, but this is not the case:).
