Potentilla recta, the sulphur cinquefoil[1] or rough-fruited cinquefoil, is a species of cinquefoil. It is native to Eurasia but it is present in North America as an introduced species, ranging through almost the entire continent except the northernmost part of Canada and Alaska.
The plant probably originated in the Mediterranean Basin. In North America, it was first collected in the 19th century in Ontario and in 1914 in British Columbia.[2] It is known as a minor noxious weed in some areas.[2] It occurs in many types of habitat, including disturbed, weedy places.

The upper part of the stem is branched and densely hairy, and it also bears some glandular hairs. The lower leaves have long stalks and the stem leaves are arranged alternately and have short stalks.

The plant may reproduce by seed or vegetatively by sprouting new shoots from its caudex. Sulphur cinquefoil flowers from June to August.[2][3]
