Ophiopogon japonica

Mondo grass, also known as monkey grass is an evergreen, sod-forming perennial. Mondo grass is quite similar to, and is often confused with Liriope, another grass-like perennial.

Mondo grass is tufted and forms clumps of dark green, narrow leaves that are great as a groundcover or as a border. They prefer a moist, shaded growing environment, and require very little maintenance.
