Hairy buttercup

Ranunculus sardous

Annual buttercup with stout, erect flowering stems up to 45 cm tall
Typical yellow buttercup flowers, up to 25 mm across, with sepals (the tiny green leaf-like structures just below the petals) that curl downwards when the flower opens. Sepals of creeping buttercup and giant buttercup remain parallel to the petals
Leaves, leaf stalks and stems are hairy
Leaf shape can be variable but the leaves are usually split into three leaflets. Leaflets may be separate and stalked or connected by leaf tissue
Leaves are shiny when young, becoming duller with age
Unlike perennial buttercups this species does not have stolons. Note however, that the stolons of creeping buttercup die back in winter so cannot be used as a diagnostic character at that time.
