Bitter Buttercup

Ranunculus acris (ra-NUN-ku-lus AK-riss)

Family: Ranunculaceae Non-native Herbaceous

Meadow buttercup is a rhizomatous herbaceous perennial in the buttercup family (Ranunculaceae), originally native to Eurasia but now naturalized across most of the US and Canada. The species epithet is from the Latin for “sharp,” apparently referring to the narrow and pointed lobes of the leaves on the upper portion of the erect stem. Meadow buttercup grows spontaneously in meadows, roadsides, pastures and disturbed area. It favors sunny positions on moist, humus-rich soil. The meadow buttercup has some of the largest flowers of the weedy species. Their shining yellow petals appear almost varnished. This species is a garden weed in most circumstances, but a welcome addition to a wildflower meadow. Although not native, this species has flowers that attract pollinators, especially hoverflies. Insects, Diseases, and Other Plant Problems: No significant problems. More information on Ranunculus .
