Lilyturf Liriope spicata

This plant is very tolerant of adverse conditions, but it can be invasive.  It is often used as a lawn alternative. It is a perennial, evergreen, tufted or rhizomatous herb used as ground cover with leaves that are straplike up to 18-inches long, dark green turning to bronze-green in winter.  This plant grows between 6" and 10" tall. Flowers are spike-like clusters of pale violet to white, 6-parted, on an elongated stem, that flower in mid to late summer. The fruit is a blue-black berry. This plant prefers light shade and fertile soil. It tolerates salt spray, heat, drought, heavy shade, but is susceptible to scale. 

It forms a dense, uniform cover, unlike Liriope muscari, which forms clumps until well established several years after planting. This plant spreads quickly by rhizomes and can invade adjacent turf areas or other ground cover beds. Therefore, this Liriope may be best suited for planting in a bed surrounded by hardscape or confined with an edging (root barrier) that is 18 inches deep. It will grow well as erosion control on banks or as edging underneath trees or around shrubs where nothing else will grow. However, like other Liriope, it will not tolerate regular foot traffic.  Liriope beds can be mowed each spring before the new growth begins to eliminate last year's unsightly foliage.  

This plant is mildly resistant to damage by deer and is drought and highly salt-tolerant.
