Landscaping With Ornamental Grasses-Best Gardening Ideas

There is nothing more graceful and calming than beholding the soft sways of tall ornamental grasses free-flowing in the wind. It awakens all your senses, from the peaceful swishing sound to the beauty of the majestic plumes billowing above towering stalks. In this post you will learn how, when, and where to add these glorious additions to your existing landscape. Read on to learn a bit about landscaping with ornamental grasses. I will also recommend a few of my favorite varieties.

How to Select the Perfect Grass For Your Area

You need to keep in mind a few things when selecting ornamental grasses.

1. Cool Season or Warm Season Grasses?

When selecting your grasses for your landscape, keep in mind the two types of grasses. A cool season grass is usually smaller. The tallest cool season grass is the Feather Reed Grass that grows 4 to 5 feet tall, however most cool season grasses grow to about 10 inches. They mature quickly and are semi-evergreen. Cool season grasses will have rapid growth in the early spring when air and soil temperatures are cooler. They bloom in the early summer.

Warm season grasses are late bloomers. They lay dormant through early spring, begin growing in the late spring and will not bloom until mid to late summer. Their blooms will last through fall. Warm season grasses can grow up to 15 feet tall.

2. Sandy or Clay Soil?

Most ornamental grasses prefer moist but well-drained and moderately fertile soil. However, you do not need these conditions to grow grass. Both varieties are very tolerant of most conditions and they are easy to grow. If planted in clay, they will usually withstand harsh growing conditions. You can ammend the clay soil by adding organic material to the hole, but it is not necessary.

Sandy soil is very light and rain will wash out nutrients. However, again, most ornamental grasses are tolerant of this and other soil conditions.

When purchasing ornamental grasses, read the soil type on the label and modify the soil as needed, but don’t go crazy with it because they will survive with little or no ammendment to the soil.

3. Sun or Shade?

Ornamental grasses prefer full sun but can thrive in partial shade. Listed below are varieties that will do well in the shade.

  • Variegated Bulbous Oat Grass
  • Mosquito Grass
  • June Grass
  • Northern Sea Oats
  • Berkeley Sedge

4. Clumping or Creeping?    

Most beginner gardeners buy on impulse, including myself when I was a beginner. You see a beautiful plant and without considering its growing habits, you purchase it. It is crucial that you consider the growing habits of ornamental grasses. One main characteristic is whether or not the grass creeps.

Three Categories of Grasses

Shutterstock MiscanthusCreeping Grasses:

Creeping grasses spread by rhizomes. They produce long rhizomes that rapidly form large colonies. They are quite invasive. The common reed grasses seen in roadside ditches are of the creeping variety. They can spread miles on end.

Look at the plant in the pot before purchasing it. If the plant has well separated stalks protruding from the pot, it is probably a creeping grass. They are hard to contain. If you choose to plant this type of grass, either plant them in an area where you wish them to spread, or contain them by planting them next to a solid barrier, or plant them in the ground in the pot.

Clumping Grasses:

These grasses form in dense tufts and will not spread like creepers. They will expand their circumferenceShutterstock Clumping Grass in time and will need to be divided. Refer to Ornamental Grasses for more on how to divide grasses.

You can determine if the plant at your favorite nursery is of the clumping variety by looking at the stems. If it is a dense clump, it is a clumping grass.

Intermediate Group/Grasses With Short Rhizomes:

This variety will creep slightly but will not be invasive. If it starts to creep, take a spade shovel and dig out the stray stems.

5. Miscellaneous Thoughts to Consider When Purchasing Grasses

  • Flood Prone Areas

If you live in a flood prone area or have low lying wet areas in your yard, particular grasses will help sop up the excess water. People also use grasses to fill in retention basins. Some varieties that do well in wet areas are Prairie Cordgrass (Spartina pectinata), and the Sugarcane Plumegrass (Erianthus giganteus ‘Red Mountain’). These varieties prefer full sun.

  • Salt Spray Tolerance

Many who live close to the sea select ornamental grasses for their yards. They look especially nice in the graceful winds that are common in these settings. However, the wind will carry salt water to your garden. Below is a list of salt spray tolerant grasses.

  • Bouteloua curtipendula.
  • Bouteloua gracilis.
  • Deschampsia cespitosa.
  • Eragrostis spectabilis.
  • Schizachyrium scoparium.
  • Sporobolus heterolepis.

Be sure to read the tag before purchasing grasses.

  • Tree Root Competition

One last item to consider when purchasing grasses is whether or not they will tolerate competition with trees with shallow roots. It will be difficult to plant a new ornamental grass close to an established tree. It is best to plant a tree in its infant stage and the ornamental grass at the same time. However, be sure it will not have to compete the root growth of the tree. Inquire at the nursery to see if this will create problems down the road.

When Should You Plant Ornamental Grasses?

If you live in an area with harsh winters, plant your grasses in the early spring. This allows them to establish their roots before winter sets in.

If you live in a milder area you can plant the grasses in the fall.

Planting ornamental grasses is rather easy. Dig a hole twice its size and depth.

Add a little Miracle Gro All Purpose Garden Soil (click here to purchase on Amazon) to the hole and mix it with the soil. This will give the plant a boost of nutrients to establish well-growing roots.

Be sure to uncurl the root ball if the plant is root bound before placing it into the ground. Gently unravel the roots and place them in the hole.

The top of the root ball should be even with the level of the surrounding soil. Refill the hole with the ammended soil and water well.

Apply some natural mulch (not dyed) on top of the soil but not touching the plant’s stalks. Leave a little space between the mulch and the plant to prevent fungi and insects from infecting the newly planted grass.

Where Should You Add Ornamental Grasses to Your Landscape?

Ornamental grasses have many functions. They can be used as an accent plant, a border, or to anchor tall trees. One other reason to include ornamental grasses in your landscape is to add whimsy and character to your yard. They will complement Asian, traditional or modern gardens. Here are a few tips on where and why you can incorporate grasses in your landscape.

1.Add for Autumn Interest. When it is starting to look a little droopy and tired, it’s nice to see a blast of color in your garden without having to purchase seasonal annuals. By planting ornamental grasses, you can include beauty and motion in your changing garden. Plant them next to summer perennials that have begun to loose their vim and vigor.

2. Use as a Border. There may be an unsightly area in your yard that you’d like to block. Use grasses to obstruct the view. Or perhaps you would like to divide your landscape into distinct areas. Use grasses to achieve that look.

3. Add Some Texture to Your Garden. If your garden looks a little lackluster, pop in a grass or 3 or 5 (remember to always add an odd number of flower/plants to your garden.)  This will add interest to an otherwise blah spot. They look lovely with perennials, annuals and shrubs. Be sure to check the mature size of the grass and plant it in proper relationship to the surrounding foliage. Refer to Beautiful Shade Garden Ideas and Low Maintence Flower Garden for more tips on adding plants to your garden.

4. Use as a Groundcover. Lawn grass is overrated. You don’t need a lush perfectly green lawn in order to make your yard appealing. By not using traditional grass in your yard, you help the environment by eliminating the leaching of harmful chemicals into the groundwater

Adding small mounding varieities of ornamental grasses as a groundcover will prevent soil erosion and weed establishment. Grasses also add beautiful color and interest, and reduce costs and the need for continuous maintenance.

5. Use Ornamental Grasses to Soften Hardscaping. If your yard has a patio made of pavers or concrete, a pebbled path, or even a pool, add ornamental grasses to create a little softness to the area. This will add motion and a more natural look.

6. Use Grasses as an Accent Piece. Consider adding the same grass scattered throughout your garden to create a more connected look.

7. Plant Grasses in Pots. Add beauty to a patio, garden, or walkway by planting grasses in pots. Use the grass as the “thriller” in the pot. For more on decorating with pots, click here.

  1. I have clumping grass growing in different places on my land. They need water every day and they grow fast. I like them, they’re beautiful, they are exactly like that photo you have over point nr.6. What is that type of grass called? It looks like the Pampas plume but less feathery.
    I also love the pink muhly grass. I have never seen it here in my area. Could it grow in a semi-desert climate and can I order seeds online?

    1. I am not sure which grass you mean. I don’t understand what nr.6 is referring to. There are many forms of pampas grass. One thinner less full pampas grass is the white feather pampas grass. Their scientific name is Cortaderia Selloana.

  2. Hi Nina, another great article about gardening. So detailed and so inspiring text! This is so welcome to me because I have been trying to find something that would fill the gap next to the fence in my yard. There is only one place where I could put ornamental grass because I have a lot of trees. Since I adore purple color my choice is definitely Purple Fountain Grass. It looks beautiful and I am absolutely fascinated! I must have this grass. It is great that it survives in warmer regions because winters here are very mild. In case I can’t find it in stores in my country, can it be ordered and how?
    Keep writing such articles and all the best,

    1. Purple Fountain Grass can be bought at the site mentioned in the article, Fast Growing Trees. To send them to Europe you first have to sign up for an international shipping forwarder. Here is a site that explains the process. https://borderoo.com/pages/buy-from-fast-growing-trees-nurserys-usa-online-store-international-shipping/

      I hope this was helpful and I’m glad you liked the article. If the site I mentioned doesn’t answer your questions about shipping, contact me and I’ll try to help you find another way to get the grass to your country.

  3. Hi Nina,

    It’s interesting to know that we need to consider the growing habits of the plants before purchasing. For example, as you mentioned in this article, clumping or creeping. Without reading your article, I might make the same mistake as many other beginner gardeners, so I can see you provide value to other readers and me today.

    I think I will plant ornamental grasses for Autumn because it will bring the other kind of beauty and motion to my garden when other summer-blooming perennials start to lose vigor. From your recommendations, Pampas Plume White Feather will be my top pick. 🙂

    Matt

    1. Yes, don’t make the same mistake I did by purchasing the wrong kind of grass! Ornamental grasses look beautiful even if you have a small yard. Pampas Plume White Feather is one of my favorites to. Send some pictures if you decide to plant them. I’d love to see them!

  4. Ornamental grasses are great as they can transform a garden. I love the colourful photos especially the pink muhly grass. It looks like a red mist! I love pampas grass as it’s so majestic. Such a lovely idea to plant grasses in pots as they compliment the pink and purple colours

    It’s interesting how different varieties are suited to different soil types. Also, what a great idea to use grass in flood prone areas. I’m sure in some cases it could lessen flood damage. It’s also helpful to know which grasses are best if you live in a coastal area. Thanks for sharing:)

    1. Thanks for commenting. Yes, using ornamentals in a flood prone area works really well and it adds beauty to your yard. Share this post with others who you think would enjoy it!

  5. Wow you have shown some inspiring ideas and options here Nina.
    Its fascinating to see all the varieties. I don’t think the full range of ornamental grasses are available in Australia – or at least I have not seen many of them yet, but you have made me curious. Here we need to be waterwise so by having a mulched garden bed with ornamental grasses, this is both less work that have the traditional flat grass, but very relaxing and soothing. This type of garden is even becoming more popular here too.

    1. I’m glad you enjoyed the post. It seems like we’re experience water issues throughout the world. Here in the US where I live on the east coast, we have had an extremely wet fall. I wish I could send some of my water your way! There are quite a few ornamental grasses that grow well without much water. I’m sure there are selections in Australia. If you substitute your regular short grass to ornamental grasses, you will probably have less maintenance and use less water.
      Thanks for the comment. Let me know if you decide to plant any. I’d love to see pictures.
      Nina
