Agoseris retrorsa, also known as spearleaf agoseris or spearleaf mountain dandelion, is a perennial herb found in western North America. It can be found in various habitats such as chaparral, scrub, and coniferous forests. The plant has a base of leaves and multiple erect inflorescences covered in wool. Its narrow leaves are spear-shaped with tooth-like lobes along the edges. The flower head, which is several centimeters wide, is lined with woolly, pointed phyllaries. The flower head contains many golden yellow ray florets, with the outer ones often being darker in color. The plant produces achenes with a plumelike pappus of white bristles.
