Dwarf Mondo Grass

Ophiopogon japonicus (Mondo Grass)

Dwarf Mondo Grass (Ophiopogon japonicus ‘Nana’) is a compact and versatile evergreen perennial from the Asparagaceae family. This miniature variety of Mondo Grass is celebrated for its dense, tufted mounds of slender, arching, dark green foliage. Growing to only 2–4 inches tall, it spreads slowly, forming a lush, carpet-like ground cover. Its small size and tidy growth habit make it an excellent choice for borders, pathways, rock gardens, or as a lawn alternative in shady areas.

During summer, Dwarf Mondo Grass produces inconspicuous, pale lilac or white bell-shaped flowers that add a subtle charm. These flowers are followed by blue-black berries that provide seasonal interest. Tolerating various conditions, it thrives in partial shade to full shade but can adapt to sun in cooler climates. Its ability to suppress weeds and resist drought once established makes it a practical, low-maintenance solution for both ornamental and functional purposes.

Care Instructions

• Planting: Choose moist but well-drained soil with a slightly acidic to neutral pH. Amending heavy clay soil with organic matter improves drainage and supports healthy growth.
• Sunlight: Position in partial to full shade for the best results. While it can handle some sun, excessive exposure in hotter climates may discolor the foliage.
• Watering: Water regularly during the establishment phase. Once mature, it becomes drought-tolerant but benefits from occasional watering during prolonged dry periods.
• Fertilizing: Apply a balanced, slow-release fertilizer in spring to encourage dense and healthy foliage. Over-fertilizing is unnecessary for this slow-growing plant.
• Pruning: Remove old or damaged leaves to maintain its neat appearance. If needed, trim back foliage in late winter to promote fresh growth.
• Spacing: Space plants 4–6 inches apart to create a seamless ground cover or 6–12 inches apart for more defined individual clumps.
• Maintenance: Divide clumps every 3–4 years to rejuvenate the plant and control its spread.

Dwarf Mondo Grass is a resilient, low-maintenance ground cover that delivers year-round beauty. Its compact size and versatility make it ideal for small spaces, shady gardens, and ornamental accents, providing elegance with minimal effort.
