Introducing the Black Mondo Grass, known as Ophiopogon planiscapus ‘Nigrescens'. The name Ophiopogon is a combination of two Greek words, pogon is a beard, and ophis is a snake.  This extraordinary grass-like perennial, has several other common names such as the black lily turf, Black Dragon, Ebony Knight, Arabicus." 

The Black mondo grass is called "black" because of the dark, almost black color of its foliage, with "nigrescens" meaning "black" in Latin. It's no wonder this variety is hailed from Asia as having the darkest foliage among all perennials!


The mondo grass will turn heads with its narrow, grass-like leaves that appear in arching clumps in an amazing blackish-purple hue depending on the light and can grow up to 8 inches tall and 12 inches wide.

It's like having a bewitching piece of the night sky right in your garden!

Mondo grass is a low-maintenance plant that is relatively disease-resistant. This ornamental plant is often used as a ground cover or border plant, and its dark foliage provides a nice contrast to other plants in the garden.

Use black mondo grass to complement silver or gold foliage plants, or combine it with succulent temperennials in shallow troughs.

The flowers of the black mondo grass bloom during the summertime, with elegant white flowers resembling tiny bells and glossy dark purple berries making their grand entrance. These bell-shaped flowers boast a delightful pink to-lilac tinting that adds an extra touch of charm.  The mature mondo grass produces globular, dark purple berries in the autumn. 

Black mondo grass can be propagated through division or by collecting and planting seeds. Division involves separating the root ball into smaller sections and replanting them in well-draining soil while collecting seeds requires patience as they can take up to a year to germinate.  

Watering Needs 

The black mondo grass requires minimal watering. As a drought-tolerant plant, this black Ophiopogon has developed an effective mechanism for storing water in its leaves. Oftentimes, people worry about underwatering their plants when they're actually giving them too much water - succulents, in particular, don't thrive well in damp soil which can lead to root problems. 

During the growing season, black mondo grass should be watered once or twice a week to keep the soil consistently moist, while in the dormant season, it should be watered once every two weeks to prevent root rot. It is important to monitor soil moisture levels and adjust watering frequency accordingly to ensure the health of the plant.

Remember, if this mondo grass is underwater, its leaves will start to turn brown and dry out. If it is overwatered, the roots can start to rot, and the leaves may turn yellow. So, it's important to only water them when the soil has dried out.

Light Requirements 

When growing indoors, your black mondo grass thrives in bright, indirect light. Just place them near southern and western windows for optimal sunlight exposure. Don't leave them languishing in dim light though - move them outdoors from time to time when natural light is scarce (like during winter). 

When growing outdoors, the mondo grass needs bright sunlight for at least 4-6 hours daily. If you're starting with a new plant that you recently bought from a nursery, don't expose it to too much sunlight all at once. Gradually increase its exposure so that it doesn't get burned by the intense rays. 

  1. If mondo grass is grown in full sun for a long period for more then 6-8 hours daily, the leaves can turn brown and scorched.
  2. If it is grown in too much shade, the leaves can become greener and less dark. Ideally, it should be grown in partial shade to maintain its dark color.

Keep an eye on your black grass leaves - if they start looking burnt, consider investing in a sunshade or moving it somewhere shadier.

Optimal Soil & Fertilizer Needs 

The mondo grass favors very airy, sandy soil that drains well. Planting them in ordinary soil will result in compacted roots, stunted growth, and, most likely, root rot. Instead, make or buy a well-draining potting mix, or ideally, use our specialized potting mix that contains over 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your black mondo grass to thrive.   

Natural fertilizers, once a year in the spring, with an equal mixture of NPK (5-10-5) also last longer and keep your soil alive by adding other beneficial compounds and microbes that encourage plant health and nutrient absorption.

Additionally, overfertilization can have a negative effect on mondo grass, causing it to grow too quickly and become weak and susceptible to disease. It can also lead to nutrient imbalances in the soil, which can further harm the plant and damage the surrounding ecosystem.  So, skip those harsh chemicals and give your black mondo some love with some awesome natural balanced fertilizer once in the spring! 

Hardiness Zones & More 

When growing indoors, this black mondo grass Ophiopogon Nigrescens prefers average room temperatures between 45°F to 75°F. It can tolerate slightly cooler temperatures, but avoid exposing it to extreme cold or drafts. It generally appreciates moderate humidity. You can increase humidity by placing a tray of water near the plant or using a humidifier. It's important to note that indoor environments tend to have lower humidity, so it's good to keep an eye on the moisture levels.

For outdoor cultivation, the black mondo grass is typically hardy in USDA zones 5 to 11. It can tolerate a wide range of temperatures, from hot summers to mild winters. However, in colder regions, it may benefit from some winter protection, such as mulching around the base of the plant. It's a fairly adaptable plant when it comes to temperature extremes.

Remember, it can also withstand a range of humidity levels, but it prefers moderate to high humidity. If the air is too dry, the leaves can become brown and crispy. To maintain the plant's health, it's important to keep the soil consistently moist and to mist the leaves with water regularly. 

Final Thoughts

Overall, the Black mondo grass (Ophiopogon Nigrescens) with its striking dark foliage, adds an elegant touch to any garden or indoor space. It forms dense clumps and grows to about 8 inches tall. It thrives in partial to full shade and can tolerate various soil types, as long as the soil is well-drained. Indoors, place it in a spot with bright, indirect light and maintain a temperature of 45°F to 75°F. Pruning is minimal, but removing damaged leaves helps keep it looking tidy. 

Be sure to add Ophiopogon Nigrescens black mondo grass to your home or garden and enjoy its low maintenance care, while admiring its impressive display year after year.

My dogs fight over it
Color: Orange, Color: Orange
Easy to use, durable, and has a great battery love. At first my dogs were curious and unsure about it, now its become one of their favorite toys. They'll stare at it while its being charged and impatiently wait for it so they can have fun again. Perfect size for most breeds.

This is a great ball for high energy dogs.
Color: Blue
I have a Belgian Malinois, so you can imagine the Maligator jaws. Just opened this today and let her play with it indoors. She LOVES IT. It wore her out and it’s a toy she can really stay focused on without needing me to throw or roll for her. It moves on its own! I supervised her play. I was hoping it was too big to get under the couch, but no. It goes right under it. I had to block off the gap so I didn’t have to keep getting it out from under for her. The outter “shell” is very durable! When she had resting moments, she chewed it pretty good - I could hear the material squeaking against her teeth. I was worried she was tearing it up, but nope! Not a mark on it. It’s easy to set up and operate. It needed charging before play. After hours of play, she was able to somehow unscrew the outter shell. This concerned me bc the smaller, inner ball mechanism came out but I saw it right away and was able to put it back together. So, make sure it’s screwed together tightly (which I thought I had done without breaking it) and check it from time to time to make sure it hasn’t loosened. This is a great ball for her incredible high energy drive. It gives her the work and fun play she needs to get tired, which I love. This toy is on the expensive end, but so far it’s worth it. Now we’ll see how long it lasts!

Love love it
Color: Blue
Best dog toy ever. I have a 1 year old boxer who is full of energy (understatement). This ball has provided more entertainment for us both than any dog toy I’ve ever purchased. Charge holds well and has a very resilient shell. I love it. Worth the price.

Great ball for limited entertainment. Replaceable outer shell is an amazing option!
Color: Blue, Color: Blue
Bought this for our 45lb, ball-obsessed Dutch shepherd/pit bull dog mix. I had one of these years ago with the hard shell and couldn’t be happier with the new foam shell. The new foam shell is much quieter and while our dog might put holes in it with his teeth, he doesn’t seem to ever pull pieces off. For engagement level, he found it VERY interesting at first and was scared to grab it, but once he got over that he started holding it in his mouth even when it shakes and just tries to keep it. Isn’t the best for fetch or anything as he has trouble letting it go when it is actively moving, but it makes him happy while he has it. We just make sure to monitor him while it is out. The ability to change the outer shell and just buy a replacement for the shell instead of a whole new toy is a lovely feature that makes me very happy to continue buying from this company.

Great Interactive Option
Color: Blue
To start, I have been very happy with this purchase. A couple of key points for me are durability and being able to keep my dog's attention. I have had it for almost a year, just a month shy, and she hasn't managed to get through the foam outer shell even though she tries real hard to do so. Let's just say, she's hard to find toys for because of her habit of finding the point of failure where she can pick and gnaw at until the toy is no longer safe for her to have. With this toy, she not only found her match, but it also has her watching, waiting, and even stalking. Only one small issue has recently occurred: the motor has started having an issue where the charge doesn't hold, and it doesn't remain on afterwards. I have reached out to Cheerble directly to see about replacing it since I am still within their 12-month timeframe, and they responded right away.
