Argentina anserina subsp. egedei Potentilla anserina subsp. egedei Potentilla egedei
Argentina egedei, known as Eged's silverweed, is a flowering perennial plant in the rose family, Rosaceae. It is also sometimes called "Pacific silverweed", though this usually (and more precisely) refers to A. pacifica.
Description
Eged's silverweed is a low-growing herbaceous plant with creeping red stolons up to 80 centimetres (31 in) long. The leaves are 10–40 cm (4–15+1⁄2 in) long, evenly pinnate into in crenate leaflets 3–5 cm (1+1⁄4–2 in) long and 2 cm broad, thinly covered with a few silky white trichomes (called hairs). The sparsity of the hairs is a useful distinction from A. anserina, which is more densely hairy.[citation needed]
The flowers are produced singly on 5–15 cm long stems, 2–3.5 cm diameter with five yellow petals. The fruit is a cluster of dry achenes.
