Sedum annuum

A tiny annual or short-lived stonecrop of sunny rock outcrops from Scandinavia and Iceland to the mountains of southern Europe and the Caucasus. It completes its life in one cool season and persists by seed, so growers should treat it like a cool-climate alpine annual rather than a long-lived succulent.
