Argentina pacifica, sometimes called pacific silverweed,[1] silverweed cinquefoil,[2] or simply silverweed,[3] is a low-growing perennial plant with pinnate leaves and yellow flowers. The edible roots were valued by indigenous peoples of the Pacific Northwest Coast.
Description
[edit]It is a low-growing (15 cm or 6 in) perennial plant. It has pinnately compound green leaves with silvery undersides. The yellow, saucer-shaped flowers appear from late spring through summer.
Taxonomy
[edit]The plant is a member of the species aggregate known as Argentina anserina or Potentilla anserina.[4]
Distribution and habitat
[edit]Pacific silverweed spreads very quickly in moist areas. Preferring salt marshes, river estuaries and shorelines, they are often seen growing alongside springbank clover.[5] They need sun and regular water.
Uses
[edit]Pacific silverweed is important in Pacific Northwest coastal indigenous cultures. Indigenous people dig for its edible roots. As an important vegetable, families maintained rights to access patches through potlatch.[6] New plants can grow from small root fragments, and with some attention families could guarantee patches persisted for generations, perhaps over thousands of years.[7] Northwest Coast peoples used to dig them in spring with yew-wood shovels before pit-cooking them or boiling them with eulachon grease. Cooked roots have a slightly bitter sweet-potato flavour. Northwest Coast peoples also washed them or mashed them into cakes and dried them for winter.[5]
