Argentina anserina (L.) Rydb.
Synonyms: Potentilla anserina
USDA Symbol: aran7
USDA Native Status: Native to U.S.
A low, 6-9 in. perennial that sends up flowers and leaves on separate stalks. Solitary, 1 in., five-petaled, yellow flowers are held on slender stems above basal tufts of pinnate, silvery foliage.
This species, also occurring in Eurasia, has recently been moved from the genus Potentilla to the genus Argentina because of the solitary flower at the tip of the stalk. The Pacific Silverweed (Argentina anserina ssp. pacifica) grows along the Pacific Coast from Alaska to southern California; the runners and stalks of its leaves lack hairs or have a few hairs that lie flat. In ancient times Silverweed was grown for food and medicine. The cooked root is purported to have the flavor of parsnips or sweet potatoes. An extract from the root has also been used to tan leather. Attractive foliage; edible roots. Raw, boiled or roasted, the spring roots have been likened to parsnips, chestnuts and sweet potatoes. Medicinally, common silverweed was used mainly as an astringent in gargles, washes and teas for reducing inflammation and stopping bleeding of the digestive tract, kidneys and skin. (Kershaw)

Soil Moisture: Moist
CaCO3 Tolerance: Medium
Soil Description: Moist loams.
Conditions Comments: Used for erosion control. Silverweed spreads by sending runners from the parent in several directions. These develop roots at nodes to form new plants.
BenefitUse Food: Attractive foliage; edible roots. Raw, boiled or roasted, the spring roots have been likened to parsnips, chestnuts and sweet potatoes.
Use Medicinal: Medicinally, common silverweed was used mainly as an astringent in gargles, washes and teas for reducing inflammation.
Conspicuous Flowers: yes
The plant is so easily reproduced by stolons that it is not worth the trouble to grow from seed. Use stolon internode
cuttings or separate rooted plantlets from parent plants in spring or summer. Seed Collection:
