Well, I think is is a hybrid called "Blue Elf", but I could be wrong, there are so many different cultivars and this was given to me, I never bought it as a labelled plant. A Sedeveria is an interspecies hybrid of Echeveria and Sedum. Some of the Sedeveria cultivars have rosettes that look more like Echeveria but this one has more of a Sedum appearance.
The amazing thing about these plants is that they can survive in such tiny containers although I am going to repot this one.
