Ornamental grasses have made a name for themselves in the landscape and garden industry, there are said to be more than” 30 species of these grasses ” which you can choose from. It’s’ believed that the popularity of ornamental grasses arose first in Germany during the mid-1930, what I love about ornamental grasses is their low-maintenance withsanding drought conditions once established along with their cold tolerance.

I have worked with many of these grasses some of which include, white fountain grass, the red fountain grass which is my favorite, muhly grass, etc.. fountain grasses are known to be perennials because they grow from year to year. These garden beauties can be seen planted in many home gardens and commercial landscape designs.

If ornamental grasses are some of your favorite plants and you want to know what to plant alongside them then continue reading and take a closer look at companion planting with ornamental grasses.

Ornamental Grass Companion Plants

Before installing ornamental grasses know exactly what you’re going for, generally speaking, most ornamental grasses range in height from 1-6 ft with 1-3 ft spread in diameter. The Pampas grass, however, can get up to 10 ft tall, some grasses have been reported to get as high as “15 ft” the taller ornamental grasses can be used as a backdrop in a garden bed.

The taller variety can also be used to fill in large gaps or spaces, smaller garden plants can be placed towards the front, I have seen red fountain grasses misplaced and at maturity, these grasses overtook the entire planting area. So ensure when installing smaller plants with the taller ornamental grasses to provide smaller plants adequate space so they don’t get chocked out by these grasses.

The goal when installing ornamental grasses with other plants is not only to go for beauty but balance as well, liriope on the other hand is an ornamental grass-like plant that gets up to 10-18 inches with 12-18 inches spread in diameter. Because of their height, liriope is used as a border plant and is normally planted in clumps or groups.

This garden beauty can also be used as a ground cover, the leaves of liriope can be either a solid green or a variegated color, the flowers which are produced by these plants are tiny, clusters with colors ranging from white, purple, and lavender. Liriope is extremely drought-tolerant, once established little care is needed these small plants are so tuff they are almost like set it and forget it.

Besides being used as a border plant liriope can be installed around the trunks of trees provided they are getting sufficient sunlight. Liriope can be installed around the base of container-grown plants as well.  Liriope can be planted along the border of a garden path walkway or driveway with larger plants being used as a backdrop.

The muhly grass is another ornamental grass that will go to work for you, during the colder months the stalks of the muhly grass produce beautiful pink to purple flowers. Though these beautiful flowers are short-lived the presence of that short period can light up your garden.

During winter time I have watched as these garden beauties transform from a green color to dazzling color. Most ornamental grasses bloom from late summer to fall, why not consider mixing it up a bit by installing both early and late blooming ornamental grasses that way once the bloom period ends for one it will be the beginning bloom period for the other.

Keep this concept in mind along with installing other perennial plants that bloom in the winter and you would have created a work of art by having a garden that’s colorful year-round.

The key to installing ornamental grasses with other garden plants is knowing the height and the spread of these plants at maturity give them that amount of spacing along with knowing their requirements(maintenance needs) in order to thrive and you will have much success as you create a garden where different plant species complements each other.
