I was out at one of the local nurseries today. After looking at the Vera Jameson sedums they have, I am pretty sure that is what I have. They also had one named Neon that had huge leafs just like my big one. I am pretty sure that was one of the sedums I had bought in the co-op so I will be looking up the Neon and see what they say about it and maybe when it blooms I will be able to tell for sure.
