Blue Lily Turf
Liriope muscari
Updated Mar 26, 2026
Blue Lily Turf (Liriope muscari), also known as big blue lilyturf, lilyturf, and border grass, is a grass-like evergreen perennial for edges and groundcover. It grows best in sun to partial shade and well-draining soil.
About Blue Lily Turf
Blue Lily Turf is a clump-forming evergreen perennial with narrow, glossy leaves that create a tidy, fountain-like shape. It is widely used for edging, groundcover, and front-of-border planting because it brings structure through the year without needing much maintenance.
Its foliage gives the garden a clean outline even when few other plants are in flower. In late summer, upright purple flower spikes rise above the leaves, adding a soft seasonal display, and these are often followed by dark berries in autumn.
Blue Lily Turf is especially useful because it adapts to a range of light conditions. It can grow in sun, partial shade, or fairly deep shade, though its overall look is often fullest and most balanced in partial shade. The plant does not dominate a space, but it gives beds, paths, and shrub plantings a more finished and intentional appearance.
How to Care for Blue Lily Turf
Watering
Keep the soil evenly moist during the first growing season so the roots can establish well and the clumps fill out properly. Early steady moisture helps the plant settle in faster and look fuller sooner.
Once established, switch to deeper watering during dry spells instead of frequent light watering. It becomes more drought-tolerant with time, but it usually looks better when the soil does not swing between extreme dryness and persistent wetness.
Sunlight
Blue Lily Turf often performs best in partial shade, especially in warmer climates where the foliage can stay richer and fresher-looking. It also tolerates full sun if the soil does not dry out too severely.
In deeper shade, it remains useful as a foliage plant, though flowering is often lighter and growth may be slower. If the clumps begin to look thin or stretched, brighter light is often more helpful than extra feeding.
Temperature
This plant suits temperate outdoor conditions and usually handles winter cold well in climates where it is commonly grown. In milder areas, the foliage often stays attractive for much of the year.
In colder regions, the leaves may look rough or tired by late winter, but the plant usually recovers strongly in spring. Exposed sites with drying winter wind can cause more foliage damage than sheltered positions.
Humidity
Average outdoor humidity is usually suitable for Blue Lily Turf, and established plants often cope well with summer heat and humidity. Good airflow matters more than trying to control moisture in the air.
Avoid overcrowded planting where air cannot move freely between clumps. Watering at soil level rather than wetting the leaves late in the day can also help keep the foliage cleaner.
Soil
Use rich organic, well-draining soil. Blue Lily Turf grows best in humus-rich ground that holds moisture evenly but still allows excess water to move away from the roots.
It is adaptable, but it performs better when the soil stays aerated rather than heavy and waterlogged. In clay soil, improving structure with organic matter and using slightly raised planting can help reduce stress.
