Packera tomentosa is a species of flowering plant in the composite family known by the common name woolly ragwort. It is native to the Southeastern United States, primarily to the coastal plain but extending in some areas inland. Its preferred habitat is open, sandy areas and granitic outcrops. It is common throughout its range. [1]

Packera tomentosa is a perennial that produces a head of yellow flowers in late spring. Its seeds have been shown to have varying masses within a singe head of flowers, perhaps as an adaptation for better dispersal in disturbed habitats.[2]
