I use the plural as this ERIN pot I showed a while ago, which was really not a lot more than throw some spare stuff in a pot and see what happens.
I’m delighted the central sempervivums have decided to flower; at least I get a nice display. There are six or seven different kinds in this one pot. 9cm wide x 4.5cm depth.

Really kind of you to say. Thank you.
