A. Common Five-Finger Or Ctnquefoil - Potentilla canadensis
In dry soil of meadows and fields, New Brunswick to Georgia, Minnesota and Texas. Flowering from April to August.
The genus Potentilla contains a number of representatives in New York, several of which are introduced species. Of these, the most common is the Rough Cinquefoil (Potentilla monspeliensis Linnaeus), with stout, erect, hairy stems and leaves, and yellow flowers in which the calyx lobes exceed the petals in length.
The Silvery Cinquefoil (Potentilla argentea Linnaeus) is a native species of dry soils or rocky places, with spreading or ascending, white, woolly-pubescent stems, leaflets green and smooth above and white-tomentose beneath, the margins revolute, and small yellow flowers.
