Crupina vulgaris (common crupina, bearded creeper) is a winter annual forb (family Asteraceae) located in Sonoma and Modoc counties where they are found on grassy sites, rangelands, forested areas, and roadsides. Crupina vulgaris reduces forage for grazing animals. It is a bigger problem in other western states and its current distribution in California have been kept in check.
