Bruso, George H.
Packera aurea (L.) Á. Löve & D. Löve
Golden groundsel, Golden ragwort, Butterweed
Synonym(s): Senecio aureus, Senecio aureus var. aquilonius, Senecio aureus var. gracilis, Senecio aureus var. intercursus, Senecio gracilis
USDA Symbol: PAAU3
Golden groundselís stout, thick, basal offshoots creep horizontally and send up erect flowering stems 1-3 ft. in height. Flowers are deep golden-yellow, daisy-like and showy. Heart-shaped basal leaves are dark-green above and purple beneath. The stem leaves are lobed. The roots colonize and the plant can achieve a groundcover effect over time.
Of the 16 species in eastern North America, an upland forest species, Squaw Weed (P. obovata), has spatulate leaves tapering at the base. Westward, on dry bluffs and prairies, Prairie Ragwort (P. plattensis) has basal leaves woolly on the underside. Woolly Ragwort (P. tomentosa), found in open woods and fields along the coastal plain from New Jersey to Texas, has long, narrow, woolly basal leaves, especially when young.
