Argentina pacifica, sometimes called pacific silverweed,[1] silverweed cinquefoil,[2] or simply silverweed,[3] is a low-growing perennial (6") with pinnately compound green leaves with silvery undersides. It is a member of the species aggregate known as Argentina anserina or Potentilla anserina.[4] The yellow, saucer-shaped flowers appear late spring through summer. Pacific silverweed spreads very quickly and makes a lovely groundcover in moist areas. They need sun and regular water.
