''Deinandra increscens'' is a species of flowering plant in the aster family known by the common name grassland tarweed. It is endemic to California, where it has been found primarily in Monterey, San Luis Obispo and Santa Barbara Counties (including Santa Cruz and Santa Rosa Islands). A few isolated populations have been reported from Kern and Merced Counties, but these are from urban areas (Cities of Merced and Bakersfield) and probably represent cultivated specimens.〔(Calflora taxon report, University of California, ''Deinandra increscens'' (H.M.
