Ohhhhhhh...
Most of the chubby wubbies are not hardy.
The other paddle-like ones are hardy.
All of phedimus, hylotelephium, petrosedum are hardy for you. (Phedimus are the ones with scalloped leaves but grow like sedum, hylotelephium go dormant and die back, mainly grown for the flowers and foilage, they look like bushes, petrosedum is just sedum but with pointy or pine-like leaves)
All of the jelly bean sedum styled ones are not hardy, and so are cleavum and trealisi, which are hardy to some extent, but I am pretty sure not hardy at 8B.
Oh and to answer your question specifically,In the newest sedum haul, only the coral reef is hardy. You can easily behead and replant for more babies,, it does very well with it. When you root the heads do it in light shade temporarily and then once they have roots move them to full sun if you want the color.
I just realized you are in zone 8B..... I thought you must have been in Florida or something to have that much tropical plants!!
