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.

    my secret

    Posted by Jan on Mar 21st 2019

    These are my secret weapon I use in areas that I want to add some color, but don't want to have to worry about caring for the plants. I use these all over the place, and it looks just fantastic, especially when I use them to border a garden or pathway.

    I went out on a limb and ordered a bunch of these plants from this website, even though I've never heard of this website before. I found them on Google, but decided to give it a chance, as I like to support small businesses. I was more than happy with the plants, they arrived in a week and in great shape! I planted a bunch of these as a border in the corner of my backyard as a border for some new landscaping I put in. It turned out great. I'll definitely be ordering from this website again.
