Potentilla is a genus containing over 300 species of annual, biennial and perennial herbaceous flowering plants in the rose family, Rosaceae. They are usually called cinquefoils in English. Potentilla are generally only found throughout the northern continents of the world (holarctic), though some may even be found in montane biomes of the New Guinea Highlands. Several other cinquefoils formerly included here are now separated in distinct genera - notably the popular garden shrub P. fruticosa, now Dasiphora fruticosa.
Some species are called tormentils, though this is often used specifically for common tormentil (P. erecta). Others are referred to as barren strawberries, which may also refer to P. sterilis in particular, or to the closely related but not congeneric Waldsteinia fragarioides.
Description
Typical cinquefoils look most similar to strawberries, but differ in usually having dry, inedible fruit (hence the name "barren strawberry " for some species). Many cinquefoil species have palmate leaves. Some species have just three leaflets, while others have 15 or more leaflets arranged pinnately. The flowers are usually yellow, but may be white, pinkish or red.
