Paronychia argyrocoma, the silvery nailwort is a plant species native to the eastern United States. It has a disjunct distribution, found in New England (Maine, New Hampshire, Vermont and Massachusetts ) and the Appalachian Mountains of the Southeast (Georgia, Tennessee , Kentucky, North Carolina, Virginia, West Virginia and Maryland) but not from New York, New Jersey or Pennsylvania in between. The species grows on rocky sites at elevations of 200–1800 m.[3][4]

Paronychia argyrocoma is a perennial herb with a woody caudex, forming mats covering significant areas of ground. Stems are prostrate to ascending, highly branched, up to 60 cm long. Leaves are leathery, lanceolate, up to 3 cm long. Flowers are borne in glomerules (clumps) of up to 25 flowers, each greenish-brown and covered with long silky hairs and spines on the calyx lobes.[3][5][6][7][8][9][10]
