Don’t let the appearance of this plant, nor its common name of lilyturf, trick you into believing it is a member of the lilium family or a grass -- it is neither one. Native to Eastern Asia, liriope is a member of the Ruscaceae family. The mature height and spread of liriope depends on the exact variety, but ranges between 12 and 24 inches tall, with a spread of 8 to 10 inches. The liriope species produces pale violet or white flowers in midsummer. The flowers are followed by blue-black berries in the fall.
In addition to its status as an edging plant, the liriope species is an ideal ground cover that thrives under a variety of adverse conditions including drought, heat and salt. Plant it under trees to help block weeds and create a lush appearance. Plant it on slopes and banks that are hard to care for. Use it as a sidewalk or driveway edging. Liriope is ideal for the edges of container gardens to give them a finished look, especially if you do not want a trailing plant hanging down the side of the container.
Though the liriope species thrives in a variety of conditions, it demands well-drained soil. Plants grown in an area that is too wet perish. Liriope preforms best in moist soil, rich in organic matter. This plant will grow in full sun or dense shade, but the best place to grow liriope is in partial shade, especially if you live in a warm climate. Plants that receive too much sun turn yellow.
Water at ground level once a week if there is not natural rainfall, since overhead watering promotes disease. The best time to water is early in the morning. This plant spreads by underground runners and is invasive. Dig plants that spread to other areas. Cut off the faded flowers to prevent self-seeding. Cut off the old foliage in late winter or mow over the top of the plant.
