Ophiopogon japonicus nigrescens, commonly known as Black Mondo Grass, is a clump-forming plant with fine, near black foliage. The foliage is complemented with flower spikes in summer, which bear tiny, pale pink flowers as it grows to 20 cm tall and the same width. Ophiopogon japonicus nigrescens nigrescens looks best when mass planted and is commonly used in rock gardens, included in borders, planted as a ground cover, or maintained in a container.

Why Choose Ophiopogon planiscapus niger?

Ophiopogon planiscapus niger stands out thanks to its deep purple-black leaves and compact clumping growth habit. In addition to its intriguing colour, Black Mondo Grass produces delicate pale lavender flowers in summer, followed by shiny black berries. The main advantage is its adaptability: Ophiopogon planiscapus niger thrives in both sun and shade, tolerates drought once established, and resists pests and diseases. It's ideal as a border edging, mass groundcover, or standout accent in mixed planting. Gardeners love using Black Mondo Grass for modern landscaping, rock gardens, and alongside pale paving stones for a striking contrast.

Best Uses for Black Mondo Grass

Looking for different mondos or foliage textures? Explore Ophiopogon Kyoto for vivid green grass-like leaves, or Ophiopogon japonicus Nana for a petite, compact form that suits smaller containers and terrace gardens.

Planting and Care Tips

Black Mondo Grass is undemanding, yet rewards a little attention during establishment. For best results: - Choose moist, well-drained soils. Suitable for both clay and sand if not waterlogged. - Space plants 15-20cm apart for dense coverage. - Fertilise in spring with a balanced slow-release fertiliser. - Mulch to conserve moisture and suppress weeds. - Trim spent flower stalks for tidy growth.

If you’re interested in a silvery look, consider Ophiopogon Silver Mist (Silver Mondo Grass), which combines easy care with subtle elegance. For larger, structural grasses, Lomandra Verday or Carex chathamica (Chatham Sedge) offer complementary architectural appeal.
