About Potentilla pensylvanica L.
Potentilla pensylvanica L., commonly called Pennsylvania cinquefoil or prairie cinquefoil, is a species of cinquefoil. In the Shoshoni language, this plant is known as Ku'-si-wañ-go-gǐp. It is native to much of northern and western North America, where it occurs across most of Canada and the western half of the United States. This species grows in many different habitat types, at elevations ranging from 2700 to 3800 meters. Potentilla pensylvanica is highly variable in overall appearance: plants may be small and tuft-like, or slender and erect. Its leaves are divided into leaflets that are deeply lobed, with hairy undersides. The inflorescence is a cluster of several individual flowers. Each flower has five yellow petals a few millimeters long, and the whole flower measures 3 to 5 millimeters in width.
