Crowfoots are a type of wildflower that belong to the Ranunculaceae family. They are also commonly known as buttercups, due to the bright yellow petals that resemble a pat of butter. Other synonyms for crowfoots include goldcups, windflowers, and kingcups. These beautiful flowers can be found growing in meadows, wetlands, and along stream banks. Although they are considered a charming sight to behold, some species of crowfoots are poisonous if ingested by livestock or humans. Crowfoots have been used for medicinal purposes in the past, with Native Americans using the plant to treat a variety of ailments.
