Ray Stephenson (Sedum, Cultivated Stonecrops, 1994, p 201) :

Sedum laxum ssp. laxum has an inflorescence that is not reflexed in bud though branches of the inflorescence are curved in towards each other. Leaves of this subspecies are glabrous, spathulate, and those of the inflorescences are narrow. Flowers are pink, deepening in shade below, with red anthers. This subspecies comes mostly from Rogue River Valley, southern Oregon, and adjacent California from very low altitudes to over 1200 m (3900 ft).
