Packera dubia, synonym Packera tomentosa, is a species of flowering plant in the composite family.[1] It is known by the common name woolly ragwort. It is native to the Southeastern United States, primarily to the coastal plain but extending into some areas inland.[2] Its preferred habitat is open, sandy areas and granitic outcrops. It is common throughout its range.[3]
Packera dubia is a perennial that produces a head of yellow flowers in late spring. Its seeds have been shown to have varying masses within a single head of flowers, perhaps as an adaptation for better dispersal in disturbed habitats.[4]
