Liriope Big Blue is an attractive, tufted evergreen ground cover plant with arching, grass like foliage. The Big Blue forces abundant blue flower spikes above the mounded blue green foliage in summer followed by clusters of black berries. This easy to grow Liriope is the perfect choice for edging or bordering partially shaded areas and prefers moist, but not wet soils. Plus, this ground cover plant can tolerate dry soil conditions once established.
As with most liriope, the Big Blue grows 12 to 15 inches tall and wide in partial sun or shade. Once established these plants are virtually maintenance free.
Likes moist, loamy soil with lime and leaf mold. We like using them as ground covers for deciduous shrubs, conifers, or broad leafed evergreens and when possible plant them in elevated areas to admire their interesting flowers.
Liriope can be used as ground cover plants under trees and shrubs and as in masses when planted on hillsides and slopes. Liriope muscari and its cultivars can also be used as low edging plants along paved areas or in front of foundation plantings.
You will find this quick growing ground cover remarkably tough. It will grow in deep shade or full sun, sand or clay. It is heat tolerant, drought tolerant as well as tolerant of salt spray, though it will not tolerate 'wet feet'; it requires moist, well-drained soil. Flowers are produced most freely in a sunny location.
Space the plants about 1 foot apart when planting. As the plants grow and mature, they can be dug and separated — usually this is done every 3 or 4 years if you want to increase your plants. Division is rarely necessary for the health of the plant.
Mow or weed eat to remove the foliage of these ground covers in late winter before new growth starts. Be sure not to injure the crown of the plant. It is important to cut back your Big Blue Liriope before spring growth begins for a healthy full looking plant.
