Packera is a genus of about 75 species of plants in the daisy family, Asteraceae. 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 a different genus based on chromosome numbers, a variety of morphological characters, and molecular phylogenetic evidence.
