Lynn it is the same as the one which is upright except maybe for the colours of the flowers. Looks like a Sedum torulsum because I don't know for how long it has been disconnected from the soil. I have some cactus pieces which I put away to callus more then six months back. Because they are in the shade, today even they look fresh. Round balls which break away from the parent plants and roll to a new place. Quite invasive some of these rolling cactus, how do they right themselves?
