Discussion
Variety sulcatum is locally common and occurs typically on limestone outcrops and cliff-faces. It is found in desert ranges of southeastern Inyo and northeastern San Bernardino counties, California, in Clark and southern Lincoln and Nye counties, Nevada, and in Washington County, Utah. In Arizona the plants occur in northern Mohave County and into northwestern Coconino County. The variety would make an ideal addition to the rock garden as a subshrub if one were willing to allow sufficient time for the plants to mature. This slow-growing plant forms dense, dark green clumps of tangled inflorescence branches and is attractive even without flowers.
