Note :

According to Ray Stephenson there are "two distinct forms ... in cultivation : the true species and a far more common imposter, a garden hybrid, which is similar but altogether larger including the flowers....Clausen thought the impostor to be a cross between Sedum bellum and a species of Echeveria, but Uhl ... suggested that the other parent appeared to be a diploid Sedum species (Sedum, cultivated stonecorps, p. 246).
