Like P. aristata, probably not native quite this far east in North America. The earliest Michigan collections are from the counties of Washtenaw (1928), Cheboygan (1929), and Delta (1934). Sandy roadsides, fields, and open ground; also pine barrens and river banks in oak forests.
The silvery white (to tawny) hairs are usually so dense and long as to conceal the surface, and they give the plant a decidedly silky appearance.
