Ophiopogon japonicus (Mondo Grass)

Noted for its attractive evergreen foliage, Ophiopogon japonicus is a desirable Mondo Grass forming dense tufts of arching, strap-shaped, grass-like, dark green leaves.

Reminiscent of Liriope, this popular evergreen grass is tough, durable, very compact and perfect for adding texture to the garden. Native to China, Japan and Korea, it is a traditional groundcover used in Japanese gardens, which is also wonderful with which to create geometric layouts in contemporary gardens.
