Just take a look at this thread and comment there if you want. Thanks. Not very magnificent

Looks like what I've been seeing in the stores lately called Opuntia Emerald Wave. Who knows what that means;)?Maybe Opuntia cochenillifera. I've seen that on Opuntias, well I've seen it on some of mine, where the new growth looks dehydrated. Once the pad gets bigger it should plump up.Remember these guys can take the sun. The more sun the merrier for this plant;).

Thanks, ladies. That was my opinion, as well. but I'd only ever seen it growing out of old cracks and forming dense mats, as in the pic. I wonder how it got there. I haven't seen any locally. It's apparent loci would be consistant with having been in with the medium it came in, but can it propagate from bits of roots after 3-4 years? Can't see that.

Hi David 👋 Thank you for the id. I have been reading a lot and I guessed that my first photo was a pubicalyx, I'm happy for the confirmation. Could the second one be cummingiana? I have picked up a few more, photos below. Krimson queen? Krimson princess? I could use an id for this last one. I've found similar photos that are labeled finlaysonii and clemensiorum, but I'm not sure which (if either) precisely match mine. Any thoughts? Thank you again, it's a pleasure 'meeting' you 🤗
