Invasive Plant

Sulphur Cinquefoil

Potentilla recta

About This Species

Sulphur cinquefoil is a long-lived perennial native to Eurasia. It invades grasslands, dry open forests, and disturbed sites such as roadsides and rangelands. A single plant can produce up to 1,600 seeds, living up to 20 years as new shoots can emerge from the main root.

How to Identify

Sulphur cinquefoil has pale yellow flowers, each with 5 heart-shaped petals. Leaves are hairy and divided into 5-7 separate toothed leaflets, arranged in a palm-like formation. Plants grow from 0.3 to 0.8 meters tall. It is often confused with the native Graceful cinquefoil (Potentilla gracilis), which is shorter and has white wooly hair on the underside of the leaves.
