Eriocoma is a genus of flowering plants in the sunflower family, Asteraceae. It is native to North America, particularly in the western United States. The genus consists of about 6 species of perennial herbs that grow in dry and rocky habitats. Eriocoma is also known as woollyheads due to the dense woolly hairs on its flower heads.
