Ground Ivy, a trailing perennial herb. Ground ivy is native to Europe, but has become a common weed in lawns and in moist woods of the eastern United States. The heart-shaped, scalloped-edged leaves grow opposite each other. The small, two-lipped, purplish flowers appear in clusters of three. Oil from ground ivy is used as a stimulant and tonic, and in treating digestive ailments.

Ground ivy is Glechoma hederacea of the mint family, Labiatae.
