Coltsfoot is a perennial, herbaceous plant that invades disturbed areas throughout much of the eastern United States. The basal leaves are heart-shaped, slightly toothed and up to 6 in. (15.2 cm) wide. The dandelion-like flowers are bright yellow in color and emerge before the leaves in early spring. Coltsfoot invades moist, open, disturbed areas such as stream banks, ditches and fields. It readily spreads both by seed and rhizomes, allowing it to form large colonies, which can displace native species. Coltsfoot is native to Europe and was probably introduced into the United States by early settlers for medicinal purposes.
