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.

Great purchase
Size: 40 Ounces, Color: Rose Quartz 2.0
I was a Stanley skeptic. I couldn’t understand what the big deal was or why the internet was freaking out. I saw the video of the Stanley cup surviving the car fire (and I think the ice was still inside). So I tried it. I drink SO much more water now! I love decorating my Stanley with all the fun accessories and it holds a nice amount of water. It feels durable and good quality. I’ve had my Stanley for a year now and I’m even considering getting another so I can have one while the other is being washed. They are easy to clean as well because of the metal inside. There are two issues I’ve had since I got the Stanley cup. Once it was dropped, and the lid broke. Easy to buy more so not the biggest issue. The cup survived the fall just fine, not a mark on it. The other issue I keep having is my lid gets stuck and becomes hard for me to open sometimes. I have a bad thumb and wrist so often I have to have my spouse open it for me. It keeps my water cold all day. If I put ice in before I go to sleep it’s still cold in the morning. I love these cups and would recommend them to anyone looking to drink more water. If you like your water bottle you will drink more water and want to bring it with you.

Very strong and cute tumbler
Size: 40 Ounces, Color: Rose Quartz 2.0, Size: 40 Ounces, Color: Rose Quartz 2.0
Great quencher to get. I got this for my self and I love it so much. It's super cute and the color I got is a light soft pink. The size is big which is great since I like having enough coffee to last me all day. It keeps my drinks cold and warm or what ever temperature it is for a good amount of time which is great for anyone who is out for long periods of time. The quality overall is very good. The handle is big, comfortable and easy to grip and the quencher fits perfectly on my gym bag. Only downside is that it did get a smudge on it after I removed the paper that it had on the bottom. I tried removing the smudge it feels sticky like glue but it didnt get removed so I had to put a sticker over it to cover it up.

Great Water Bottle!
Color: Off Road, Size: 30 Ounces
I was looking for an insulated water bottle that would actually fit in a standard cup holder. I decided to try the Owala FreeSip Sway Insulated Stainless Steel Water Bottle. Upon receiving it, I noticed that it felt solid in my hand. The mechanism worked very smoothly with a simple button press opening the lid. Once open, you can choose to either use the included straw or tip the bottle and drink from the chug spout. In addition to it fitting in my cup holder, I needed it to be leak proof. This bottle is leak proof, and the spout can be locked by engaging a lock in the back. The rugged flip handle is also a convenient way to carry the Owala when it's not in the water bottle holder on my backpack. I hand wash the body of the bottle, but the top disassembles easily and can go right in the dishwasher when I want a deep cleaning. The bottle has a wide opening, so it is very easy to clean the inside. This has quickly become my favorite water bottle due to its ease of cleaning, good insulation, ability to fit in my cup holder, solid construction and materials, and the option of using the straw or chug spout. I have the 30 ounce bottle, but I am going to be picking up a 40 ouncer also. You won't regret purchasing one! I have used the bottle for a couple of weeks now, and here are my observations: It has gone on two camping trips, and it has proven to be durable. I have placed the Owala on its side on my passenger seat (just to test it...it fits perfectly in my car's cup holder!). It did not leak a single drop on a long road trip. On my camping trip, the water in the bottle was still ice cold the next morning, so it keeps cold beverages very cold!

The Perfect Bottle
Color: Dreamy Field, Size: 40 Ounces
I do not leave reviews, but I had to for this. This is the PERFECT water bottle. It has a handle, it's leak-proof, with a lock, so you don't have to worry when your baby decides to play with the bottle and tips it over -- there won't be a spill! Straw and sip option are perfect and I love that the straw is inside the cup so I don't have to worry about my kids hurting themselves when they drink from the cup. 40 oz is a great size, holds a lot of water but tapered bottom perfectly fits in the cup holder. So easy to use, my 4 year old has no issues. Cleaning takes 3 minutes. I recommend to absolutely everyone.

Great quality, beautiful colors!
Color: Black Cherry, Size: 30 Ounces, Color: Black Cherry, Size: 30 Ounces
I love my Owala! The colors are beautiful. It's easy to wash out and clean. I like the lock function. There's been a couple of times that I've put it in my purse without locking it and the button accidentally pressed open and spilled. So the lock fuction definitely comes in handy! It's easy to carry around with the handle. It doesn't feel overly big/bulky. It fits in my van cup holder just fine. My toddlers are able to drink from it using the straw function without spilling and making a mess. If I put a lot of ice in it, it usually still has ice the next day. It stays cold for quite some time. The overall quality is great! I'm pretty rough on it and it has minimal scratches so far. I definitely plan on buying more colors in this size!
