Lilyturf

Dry shade is the hardest brief in planting design, and Ophiopogon intermedius is one of the few plants that answers it without complaint. Narrow arching dark green leaves form a low tuft that spreads slowly by short stolons into an even, weed-suppressing mat.
Small lilac-white flowers appear on short stems among the foliage in summer, followed by blue-black berries, but this is a plant grown for texture and permanence rather than for display.
Lilyturf is the quiet answer to dry shade, holding a clean even texture in the conditions that defeat most ground cover.
