Perhaps only second to wild violet as the difficult-to-control weed that most often frustrates professional lawncare operators and homeowners. Ground ivy, also known as creeping Charlie, is an aggressive perennial that is ideally suited to many landscape situations. It prefers moist, well-fertilized, shades sites maintained at a low mowing height.
Ground ivy spreads by above-ground runners (stolons) and can quickly overtake large areas of real estate. Hand removal of ground ivy may be therapeutic but is usually not effective.
Ground ivy is characterized by its coin-shaped leaves with scalloped (crenate) edges and square petioles and stems. All plant parts have a strong mint odor when crushed or cut. Ground ivy's orchid-like purple flowers appear for a short time in mid-May. The flowers can easily be overlooked as they are often exhibited below the turf canopy.
