Ranunculus arvensis, commonly known as corn buttercup or field buttercup, is an annual herbaceous plant native to Europe and parts of Asia. It is characterized by its small, bright yellow flowers with five glossy petals that bloom in late spring to early summer. Corn buttercup thrives in open fields, grasslands, and disturbed soils, often found in agricultural areas and along roadsides. This plant is valued for its hardy nature and its ability to thrive in various soil conditions. Despite its somewhat weedy appearance, Ranunculus arvensis plays a role in supporting pollinators such as bees and other insects, contributing to the ecological diversity of the habitats it occupies.
