I think the leaves (what do you call them on sedums of this style?) look closer to album; they are more rounded than many pictures I've seen of acres. But I really don't know.
The closest match I've found is S album 'Coral Carpet', but the leaves/needles on the mystery sedum appear to be narrower and I'm not sure of the size of the coral carpets in the pictures.
For reference it looks kind of like a mini S rupestre 'Blue Spruce', but the needle tips are more rounded, not pointed. It is also more green, and it is less than half the size (currently about 1/4" wide).
Any ideas?
