Liriope can be used as a groundcover under trees and shrubs and as a massed planting on slopes and banks. Liriope muscari 'Variegata' and its cultivars can also be used as low edging plants along paved areas or in front of foundation plantings. Liriope is remarkably tough. It will grow in deep shade or full sun, sand or clay. It can endure heat, drought and salt spray, but will not take;wet feet; it requires moist, well-drained soil. Flowers are produced most freely in a sunny location. Space the plants about 1 to 2 foot apart when planting. As the plants grow and mature, they can be dug and separated; usually this is done every three or four years if you want to increase your plants. Division is rarely necessary for the health of the plant.
