Some postemergence herbicide products labeled for control of creeping buttercup. This weed can be suppressed or controlled with various postemergence herbicides. Photo: Peter Landschoot, Penn State Management and controlĬreeping buttercup infestations can be reduced by improving turf density through fertilization, regular mowing, improved drainage, reducing irrigation, and use of turfgrasses well-adapted to site conditions. Yellow flowers of creeping buttercup showing overlapping petals and multiple stamens in the center. Clusters of stamens and pistils are in the center of flowers. Flowers are bright yellow, with five to seven rounded, overlapping petals. Photo: Peter Landschoot, Penn Stateįlower stems give rise to single flowers, approximately ½ to ¾ inch in diameter. The central leaflet on some leaves is positioned on a short stalk. Leaves of creeping buttercup showing three leaflets with serrated margins and deep sinuses. Leaf and flower stems are slightly hairy and red or purple near the crown. Margins of leaflets are coarsely serrated towards the top with relatively deep sinuses. Leaf surfaces are dark green, frequently with light spots or blotches. Individual mature leaves are typically 1.5 to 3 inches long and 1 to 1.5 inches wide. The center leaflet is often extended on a short stalk. Leaflets are somewhat variable in shape, ranging from wedge-shape to oval. Some creeping buttercup leaves have three leaflets, whereas others are simple with three lobes and deep sinuses. Photo: Peter Landschoot, Penn State Identification Creeping buttercup plants form yellow flowers in May and June, which eventually produce seeds.
Stolons grow prostrate along the soil surface, producing shoots and roots at nodes. New plants form a rosette of leaves and stems, with some stems functioning as stolons.
