About Salvia pinguifolia (Fernald) Wooton & Standl.
Salvia pinguifolia, commonly called rock sage, is a species of flowering plant in the family Lamiaceae. It is native to southern Arizona, southern New Mexico, and western Texas in the United States, as well as Chihuahua in Mexico. This species grows on rocky slopes at elevations between 2,000 and 7,000 ft, which equals 610 to 2,130 m. Its scientific specific epithet comes from the Latin words pinguis, meaning "grease," and folium, meaning "leaf," which refers to the texture of its leaves. Its leaves range in shape from ovate-deltoid to oblong elliptical. During the Late Wisconsin glacial period, Salvia pinguifolia had a larger geographic range than it does today. For example, it was present in the Waterman Mountains of southeastern Arizona, located in northern Pima County, during that earlier epoch, but it no longer grows there currently.
