Sedum debile

A small, mat-forming stonecrop of rocky mountain slopes in the Great Basin and northern Rockies, recorded mostly between 1,300 and 3,600 m. It is a true cold-climate plant: snow-covered and frozen in winter, sunny and dry in late summer, so it does far better in an outdoor rock garden or trough than indoors.
