Field balm, gill-over-the-ground, gill, creeping Charlie, robin-runs-away, cat's-foot.
Ground-ivy is found in dams and shady places, especially in thickets, from Newfoundland and Ontario to Georgia, Tennessee, Kansas, and Colorado.
This small herb has numerous creeping, leafy, hairy stems sometimes 18 inches long, commonly branching at the base. The opposite leaves are round kidney-shaped, bluntly toothed, green on both sides, and one-half to 1 1/2 inches in diameter. The stems of the lower leaves are commonly longer than the leaves. The blue and white tube-shaped flowers are borne, few in a cluster, in the axils of the leaves from March to May.
