Mostly grown for its attractive foliage, Blue Lily Turf is an evergreen tuberous perennial forming a dense clump of narrow, arching, dark green leaves. Blooming for weeks in late summer and fall, erect spikes of thickly clustered, small violet-purple flowers appear on the stems. The blooms give way to round, shiny, black berries which often persist into winter. Hardy and compact, lily turf can be a great turf alternative.
