description Buttercup Overview
Buttercup is a common name for flowering plants in the genus Ranunculus, including Ranunculus acris, a perennial species widespread in European meadows. The flowers typically have glossy yellow petals, and the reflective appearance is linked to the structure of the petal surface, which combines several layers of cells to direct light.
