Liriope (Lily Turf) are evergreen herbaceous perennials forming compact clumps or spreading patches of narrow, arching leaves. In late summer, they boast erect spikes of thickly clustered, violet-purple flowers which are followed by shiny, black berries. Hardy, Lily Turf is a popular, alluring plant, particularly handsome when grown in large swaths or undulating rivers. A wonderful edging plant for walks, paths, pool decks, narrow spaces, this is also an excellent choice for placing in front of shrubs or under trees for a fluffy effect. Liriope can be used as a lawn grass substitute too. Deer resistant, it is also heat, humidity and drought tolerant.
