(Formerly known as O. nigrescens ‘Black Dragon’)
Looking much like a black Liriope, Black Mondo Grass is a compact, densely growing, clump forming, evergreen, grass-like plant. When grown in full sun in the north, the foliage emerges purplish-green and then turns nearly jet black. It has a softly arching habit.
From early through midsummer, short spikes of light purple to white flowers (much like those of Liriope) are produced, followed by purplish black berries in the fall.
Black Mondo Grass adds dramatic flair to combination containers but can also be grown en masse as a low groundcover. Use it as a foil for silver or gold foliage plants or combine with succulent temperennials in shallow troughs.

Black Mondo Grass grows best in moist, well-drained soil with a neutral to slightly acidic soil. In northern climates, it can be planted in full sun, but partial shade is recommended in warmer zones. Sunlight draws out the deep black foliage color. Though it is reliably hardy in zones 6 and warmer, it will also overwinter in zone 5 if sited properly. This plant has an average to slow growth rate, so it will not overtake surrounding plants. Divide in early spring if desired.
