Argentina anserina (L.) Rydb.
Rosaceae (Rose Family)
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,
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
) 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)
