Ericameria laricifolia is a North American species of flowering shrub in the family Asteraceae known by the common name turpentine bush, or turpentine-brush. It is native to the southwestern United States (Arizona, New Mexico, western Texas , southwestern Utah, southern Nevada, southeastern California ) and northern Mexico (Chihuahua).
Ericameria laricifolia grows in desert scrub and woodlands. It is a shrub reaching 50–100 cm (20-40 inches) in height, is generally hairless, somewhat glandular, and aromatic. It sometimes has naked stems at the base but the upper branches are densely foliated in needlelike, pointed leaves one to three centimeters (0.4-1.2 inches) long. The many erect branches bear inflorescences of bright golden yellow flower heads, each with up to 16 long disc florets and as many as 6 ray florets.
