Buttercup, Creeping, Ranunculus repens

Life Cycle

Perennial.

Propagation

Reproducing by seed and by trailing horizontal stems which root at the nodes (Fig 1).

Stems

Stems (Fig 8) prostrate or sometimes nearly erect and 20-30cm high, ranging from smooth to densely hairy.

Leaves

Leaves (Fig 6,7) alternate (1 per node), often clustered, mostly with long stalks; the blades 3-parted and the middle segment with a distinct short stalk; each segment again lobed and toothed.

Flowers and Fruit

Flowers (Fig 4) and seed heads (Fig 5) similar to Tall buttercup. Flowers from April to July.

Habitat

Creeping buttercup occurs in scattered localities throughout Ontario in habitats similar to those of Tall buttercup, but is much less common. It grows particularly well in moist or poorly drained situations and it is often a bad weed in well-watered lawns.

Distinguishing Features

It is distinguished from Tall buttercup by its prostrate stems which root at the nodes (Fig 1) and by the 3-parted leaf blade in which the central or terminal lobe has a distinct stalk (Fig 6 and 7).

Toxicity

Like Tall buttercup this species also has a bitter, acrid juice and may be poisonous to livestock.
