I agree, it does look close, but I do question the X on the plant tag. That would indicate that the plant is a hybrid rather than a species....but, S adolphii may be one of the parents.
I do agree that sedum X adolphii seems to have something to do with this plant, Janet. The link I posted was for info on sedum X adolphii "Golden Sedum" which looks quite similar
This was tagged as just Sedum X. Usually at the greenhouse I buy succulents from they have genus and species, so I wasn't sure if the X meant it was a hybrid or if they just didn't know what the species was!
