==Description==
It is a herbaceous, stoloniferous perennial plant growing to 50 cm tall. It has both prostrate running stems, which produce roots and new plants at the nodes, and more or less erect flowering stems. The basal leaves are compound, borne on a 4–20 cm long petiole and divided into three broad leaflets 1.5–8 cm long, shallowly to deeply lobed, each of which is stalked.〔Parnell, P. and Curtis, T. 2012. ''Webb's An Irish Flora.'' Cork University Press. ISBN 978-185918-4783〕 The leaves higher on the stems are smaller, with narrower leaflets and may be simple and lanceolate. Both the stems and the leaves are finely hairy. The flowers are bright golden yellow, 2–3 cm diameter, usually with five petals, and the flower stem is finely grooved. The fruit is a cluster of achenes 2.5–4 mm long. Creeping buttercup has three-lobed dark green, white-spotted leaves that grow out of the node. It grows in fields and pastures and prefers wet soil.〔Blamey, M. & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''. ISBN 0-340-40170-2〕〔Flora of NW Europe: (''Ranunculus repens'' )〕
