I have blooms on that one:
Posted that in the Plant ID thread also but, yanno, in case someone here knows it I thought I'd double up too.
Honestly, looking in the database didn't help, even with the blooms. Going to google next I suppose. Also, I know this isn't really a sedum, or I think it isn't! so my apologies for wending off course here.
ETA: From google, it looks like this is indeed Pachyveria of some kind.
