Black Mondo Grass (Ophiopogon planiscapus ‘Nigrescens’) is a low- growing, ornamental grass that originates from Japan.
Very low maintenance and versatile, it can be grown in mass, containers, as border plants or even a groundcover. It can also feel right at home near edges of ponds and streams or in bog, rain or water gardens. Mondo grass grows to 8-12 inches in zones 6 to 9. The plants benefit from loamy, slightly acidic soil. It prefers partial sun to partial shade in a moist environment.
Black Mondo grass has purple/black broad evergreen leaves. It sprouts lovely lavender/white flowers in the summer amid racemes, which produce small blue, inedible berries.
Black Mondo Grass can be propagated by division from established runners.
