'''''Packera''''' is a genus of about 75 species of plants in the daisy family, Asteraceae.<ref name=POWO_298624-2/> Most species are commonly called '''ragworts''' or '''grounsels'''. Its members were previously included in the genus ''Senecio'' (where they were called ''aureoid senecios'' by Asa Gray) but were moved to genus ''Packera'' based on chromosome numbers, a variety of morphological characters, and molecular phylogenetic evidence.<ref name="fna"/>
