Echeveria, Firecracker, moulded wax, hen and chickens or painted lady. Take your pick. The chickens are your new plants. They root easily in a sandy compost, especially in spring after they have dried out for a week. Go easy on the watering. It likes a rest period in the winter.

If the whole plant is coming away from the compost then check for Vine weevil grubs in the pot.

Thanks for that Daphne, I have a friend who has already expressed an interest in having one. Now I know what to do.
I hope your wrong Owdboggy...better check my other plants too I guess. :(

The answer to what's this plant, Daphne63 got it good, I've got mine in a large Alpine bed.

Thanks Sunne, does that mean it is winter hardy??
