Black Mondo Grass

Ophiopogon planiscapus 'Nigrescens' (Black Mondo)

Black Mondo Grass (Ophiopogon planiscapus ‘Nigrescens’) is a striking evergreen perennial from the Asparagaceae family. Known for its dramatic, grass-like foliage, this plant features deep purple-black, arching leaves that form dense clumps. Growing 6–12 inches tall and wide, it creates a bold contrast in gardens, especially when paired with lighter-colored plants.

In summer, Black Mondo Grass produces small, bell-shaped flowers in pale pink or lavender, adding a subtle charm. These blooms are followed by dark purple to black berries, providing additional seasonal interest. Thriving in partial shade to full sun, it adapts well to various garden settings, including borders, rock gardens, and containers. Its slow growth and low-maintenance nature make it a favorite for creating elegant, modern landscapes.

Care Instructions

• Planting: Choose humus-rich, well-drained soil with a slightly acidic to neutral pH. Amend heavy soils with organic matter to improve drainage.
• Sunlight: Position in partial shade to full sun. In hotter climates, partial shade helps prevent leaf discoloration.
• Watering: Water regularly during the establishment phase. Once mature, it becomes drought-tolerant but benefits from occasional watering in dry periods.
• Fertilizing: Apply a balanced, slow-release fertilizer in spring to encourage healthy growth. Avoid over-fertilizing, as it may reduce the intensity of the foliage color.
• Pruning: Remove old or damaged leaves to maintain a neat appearance. Trim back foliage in late winter if needed to encourage fresh growth.
• Spacing: Space plants 6–12 inches apart for a dense ground cover or 12–18 inches apart for individual clumps.
• Maintenance: Divide clumps every 3–4 years to rejuvenate the plant and control its spread.

Black Mondo Grass is a versatile and eye-catching addition to gardens. Its unique foliage color, combined with its adaptability and low-maintenance requirements, makes it ideal for creating dramatic contrasts and year-round interest in landscapes. Whether used as a ground cover, edging, or container plant, it adds sophistication and depth to any garden design.
