About Artemisia rothrockii A.Gray
Artemisia rothrockii A.Gray is a North American sagebrush species, commonly called timberline sagebrush and Rothrock's sagebrush. This species is endemic to California, native to sections of the Sierra Nevada, the White Mountains, and the San Bernardino Mountains. It has been documented growing on the Kern Plateau, Mount Dana, Angora Peak, and in the area around Fallen Leaf Lake. It grows in the dry transition zone between mountain meadows and forests, and can also tolerate wet conditions, surviving waterlogging during snowmelt. Artemisia rothrockii occurs at elevations between 2000 and 3500 meters. It is a mountain shrub that reaches heights of 20 to 50 centimeters, and grows many upright stems from a narrow trunk. Its evergreen foliage is dark green, glandular, sticky, and strongly aromatic. New twigs and leaves are somewhat woolly, while older parts of the plant are hairless. Its narrow inflorescence holds clusters of flower heads, which are lined with rough, shiny, slightly hairy phyllaries and contain yellowish disc florets. The fruit is an achene up to 2 millimeters long, which sometimes has a pappus. This species is named for American forester Joseph Trimbel Rothrock, who lived from 1839 to 1922.
