Potentilla tanacetifolia, commonly known as tansy‑leaved cinquefoil, is a plant in the family Rosaceae, native to southern Siberia, Mongolia, and northeastern China. The genus name Potentilla derives from the Latin potens (“powerful”), alluding to the plant’s reputed medicinal strength; the specific epithet tanacetifolia combines Tanacetum (the name of another genus) with the Latin folia (“leaves”), indicating that its foliage resembles that of tansy.
