Ophiopogon planiscapus 'Nigrescens' – Black Mondo Grass

Create bold contrast with the near-black foliage and graceful texture of Black Mondo Grass.

Ophiopogon planiscapus 'Nigrescens' is an evergreen, grass-like perennial, not a true ornamental grass. Its narrow, arching leaves mature to deep purple-black, forming low clumps that gradually spread into a striking groundcover. Small pale lavender flowers appear in summer, followed by dark berries. Pair Black Mondo Grass with chartreuse foliage or light-colored stones to make its rich color stand out, or tuck it along a shaded pathway and into mixed containers for a dramatic finishing touch. Provide well-drained soil and protection from intense afternoon sun in hot climates.
