Mondo Grass Cropped

  • Height 12 to 15”

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 18 to 20 inches apart in mass plantings or when planted as an edging.

Time of Order:

Winter to Early Spring

  • Is it warm enough to plant in the customer’s growing zone?
  • What areas does the plant has to travel through from our nursery to your home?
  • Is the plant at the nursery ready to ship.
    • The plants from the South will naturally be ready sooner than the plants from the North (If you have questions or concerns about when a plant will ship please email us at info@plantaddicts.com)


  • If there is extreme heat we’ll delay shipping.  
    • We’ll have to review what areas the plants are traveling through along with your location

Fall into Winter

  • We’ll ship all the way up to the end of the fall planting season!


  • Get your order in now to reserve you plants for Spring planting!

Once your plant is shipped you’ll receive an email with tracking information. Depending on the above criteria we’ll ship your plant(s) towards the beginning of the following week from your order date. We put together this helpful guide for what to do when you receive your plants in the mail.

It is important to know that all of our plants are clearly labeled for which growing zones the plant can survive in. The plants are thoroughly trialed and tested in every growing zone before we state the plant can grow in a zone. Again, our #1 priority is to ship the plants to you healthy and ready to thrive in your location. So we will do everything in our power to do so.

    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.
