Brickellia oblongifolia (Mojave brickellbush) is North American species of plants in the sunflower family. It is widespread across arid and semi-arid regions in the western United States and Canada, from British Columbia south to southern California, Arizona, and New Mexico. Brickellia oblongifolia is a perennial herb of subshrub up to 60 cm (24 inches) tall, growing from a woody caudex. Flower heads sometime appear one at a time, sometimes in groups of several, each head cream-colored or pale yellow-green, containing disc florets but no ray florets.
