Mondo Grass

Ophiopogon japonicus (Mondo Grass)

Mondo Grass (Ophiopogon japonicus), an evergreen perennial from the Asparagaceae family, enhances landscapes with its graceful, grass-like foliage and year-round charm. This plant forms low, dense mounds, typically reaching 6–12 inches in height while spreading slowly. Its slender, arching leaves range from vibrant green to deep black, depending on the variety. Gardeners often use it as a ground cover, for edging pathways, or to fill garden gaps with lush elegance.

During summer, this versatile plant produces bell-shaped flowers in pale lilac or white, followed by ornamental blue-black berries that provide additional visual interest. Thriving in diverse environments, it tolerates full sun, deep shade, and even poor soils. Its ability to suppress weeds, control erosion, and serve as a lawn alternative adds to its value in gardens and landscapes.

Care Instructions

• Choose well-drained soil with a slightly acidic to neutral pH. Amending heavy clay soil with organic matter improves drainage and promotes healthier growth.
• Place Mondo Grass in partial to full shade for the best results. While it handles full sun in cooler climates, excessive exposure in warmer regions can discolor the leaves.
• Water regularly during the establishment phase. Once the plant matures, it becomes drought-tolerant but benefits from periodic watering in prolonged dry spells.
• Apply a slow-release, balanced fertilizer in early spring to encourage vibrant foliage. However, avoid over-fertilizing as it may hinder flower production.
• Trim damaged or old leaves to maintain a tidy appearance. If the foliage looks worn, cut it back to ground level in late winter to allow for fresh growth.
• Space plants 6–12 inches apart to ensure proper airflow and achieve uniform coverage without overcrowding.
• Divide clumps every few years to invigorate growth and control spread, ensuring the plant remains attractive.

Mondo Grass is a low-maintenance, ornamental choice that suits many garden designs. It adds elegance to pathways, borders, and shaded areas. With minimal care, it thrives year-round, offering reliability, beauty, and versatility. This perennial remains a favorite for gardeners who seek understated sophistication.
