Salvia greggii

Salvia greggii, the autumn sage, is a herbaceous perennial plant native to a long, narrow area from southwest Texas, through the Chihuahuan Desert and into the Mexican state of San Luis Potosi, typically growing in rocky soils at elevations from 5,000 to 9,000 ft (1,500 to 2,700 m). It was named and described in 1870 by botanist Asa Gray after Josiah Gregg (1806–1850), a merchant, explorer, naturalist, and author from the American Southwest and Northern Mexico, who found and collected the plant in Texas.
