This is not Graptopetalum paraguayense but probably one of the G. amethystinum x paraguayense hybrids (G. 'Marquise de Sévigné', G. 'Snow-White', or G. 'Victor Kane'). The hybrids are nearly indistinguishable from each other, so I think this should be moved to the genus page. Notice how the leaves are thicker than G. paraguayense which is due to amethystinum parentage.
