Best known for its tall, grass-like, narrow leaves, Ophiopogon nigrescens or “Black Mondo Grass” is a perennial, native to Japan, that is a member of the lily family. Its leaves, clumped together in the middle and arching outwards, can rise to a foot high.
This plant is at its best when used in bunches as edging along a garden, sidewalk, stream, rock garden, fairy garden, or entryway. In the summertime, it produces flowers of a white and deep lavender color, and autumn brings purple berries.
Black Mondo Grass is not always winter hardy, so you will want to keep it protected in the coldest and driest months of the year. Black foliage color, which some say is the blackest foliage of any perennial, develops best when the plant is located in the sunshine.
