Dark green clumps of grass-like leaves makes Mondo Grass, Ophiopogon japonicus, an excellent evergreen groundcover or edging plant. Small spikes of lilac-colored flowers appear in summer. These are evergreen in most parts of the country and provide a low-maintenance groundcover option. Mondo grass is also great for foundational plantings to add green color to any landscape.
This plant is also known as Monkey Grass and is resistant to weeds and diseases. There is also dwarf mondo grass if you are looking for something smaller, which grows around 6" tall.
Mondo Grass Care
Plant in well-drained soil and water regularly to establish. Water weekly, once established, and more often during extended periods of extreme heat. Protect from harsh, afternoon sun. Clumps can be divided in early spring every 2 or 3 years.
Mondo Grass Spacing
Plant 4 to 12 inches apart in mass plantings or when planted as an edging. The closer you plant each plug, the faster it will fill in for complete coverage. You should also stagger between rows for the best coverage.
