Liriope is a low-maintenance groundcover for the most challenging sites. Spikes of blue-violet blooms complement deep green arching foliage in late summer, and almost black berries in fall. Plants tolerate a range of conditions from full sun to shade, clay to sandy soils, and wet or dry sites. Liriope provides excellent erosion control, and is often used as a lawn alternative or groundcover. Evergreen foliage in warm southern climates.
