This is not xG. 'Ghosty', but the parent plant, Graptopetalum paraguayense. I propose that this image be moved to Ghost Plant (Graptopetalum paraguayense)

about this and gingin's other two related pictures




If you compare these images to the ones on the page for 'Ghosty'

Ghost Plant (XGraptosedum 'Ghosty')

you can see that 'Ghosty' makes fuller rosettes and the leaves are more chunky. 'Ghosty' is notorious for misidentification and its origins are not entirely clear, so there does generally seem to be some confusion in the marketplace about names in this group.
