Ground Ivy (Glechoma hederacea) vs. Purple Deadnettle (Lamium purpureum)
Updated April 18th, 2025These introduced species are sometimes confused; both are common in gardens and they can grow together in the same habitat. They can be easily distinguished by leaves, flowers, and life cycle. Glechoma hederacea ranges much farther north, can survive in mowed lawns, is present year-round, and is more restricted to partly-sunny exposures, whereas Lamium purpureum inhabits a broader range of lighting conditions, from full sun to areas under a canopy of deciduous trees, and is absent in summer.
