Coleogyne ramosissima or blackbrush, is a low lying, dark grayish-green, aromatic, spiny, perennial, soft wooded shrub, native to the deserts of the southwestern United States. It is called blackbrush because the gray branches darken when wet by rains. It is in the rose family (Rosaceae) and is monotypic (the only species in its genus).
