Potentilla argentea, known as hoary cinquefoil,[1] silver cinquefoil,[2] silvery cinquefoil,[3] or silver-leaf cinquefoil,[4] is a perennial herb (or forb) in the family Rosaceae. Potentilla argentea is native to Europe, Asia Minor, and Siberia,[3] and is introduced throughout temperate areas in North America and in New Zealand.[1]

Description

The basal leaves are palmate, generally in groups of five, grey-green above and silvery-white and tomentose below. With multiple flowers per plant, the flowers bloom a few at a time from late Spring to mid-Summer. Flowers are about 1 to 1.5 cm wide, and are five-petaled, with the petals rounded, wedge-shaped, and separated, sulphur-yellow coloured, in leafy cymes. Its growth habit is upright or sprawling, to 0.5 m high.[1][3][5][6]
