Ornamental Grasses in the Garden

For gardens that don’t receive heavy frost you can’t beat Red Fountain Grass for color and drama

Throughout the year I am asked for design help and plant suggestions but in the fall especially I hear the request, “I’d love to add more grasses to my garden.” There’s no doubt that the movement and sound of ornamental grasses in the landscape adds another dimension to our experience. Many grasses and grass-like plants use less water than other plants, too.

Grasses are versatile plants and come in all sizes, from ground-huggers to shrub-like clumps. Some form upright tufts, some look like mop-top mounds and others form arching fountains. They easily adapt to the same conditions most garden plants thrive in, rarely needing any special soil, preparation or maintenance. And more subtly, their gentle movement and soft whispering sounds can bring your garden to life as no other plants do.

There’s an ornamental grass for every type of garden. Whether you are striving to create the perfect perennial border or have a hot dry slope, grasses can work in harmony wherever you place them. There are some that are made for the shade, some that are perfect additions to a small water feature and many that are invaluable in container gardening.

Most grasses require little care, minimal fertilizer, only occasional grooming and just enough water to meet their needs. Diseases and insect pests are rare. They have succeeded because of their adaptability and have evolved to suit almost every environment and climate on earth.

In addition to true grasses plants like lomondra and phormium are beautiful year round.

Grasses are distinguished from other plant families by their growth habit. They grow upward from the base of a leaf or shoot and can regrow from the crown when cut back. True grasses generally have extensive root systems which help control erosion. There are other grasslike plants that resemble grasses in their growth habits and are often some of the best companions for interplanting with grasses. These include New Zealand flax, carex family sedges, chondropetalum, kangaroo paw, lomandra, montbretia, liriope and their cousins ophiopogon.

If you are trying to create a focal point or destination in your garden and think the texture, light and movement of a grass would be perfect, look to the taller varieties. Stipa gigantea (Giant Feather Grass) is a semi-evergreen grass which grows 4-6 feet high and makes a stately specimen with narrow, arching foliage and shimmering gold panicles that reach even taller. The flowers open early in June silvery-purple and mature to shades of wheat. Large plants in full flower are a spectacular sight. Their tufted, clumping form makes them suitable as accents anywhere. They take drought conditions once established but also will grow with regular garden watering. The beautiful flower spikes are good in dried arrangements.

Pheasant Tail grass is another easy to care for ornamental grass

Besides texture, grasses provide color for your garden, too. Who hasn’t admired the burgundy foliage of Red Fountain Grass? it’s one of our most popular grasses with its fox-tail like coppery flower heads. Another favorite of mine for color is Japanese blood grass, You’ll love this grass when you place it so the sun can shine through the brilliant red blades. This grass spreads slowly by underground runners and grows in sun or partial shade forming an upright clump 1 to 2 feet tall. Pink Muhly grass will stop traffic when in bloom.

Pennisetum foliosa takes a beating and keeps on ticking.

Are sections of your garden hot and dry? Grasses are survivors and are good choices for sunny spots that get little irrigation. Good drainage is a must for these plants so amend the soil with plenty of organic matter before planting. Combine drought tolerant grasses with companion plants and a few accent rocks to complete your dry theme. Good combinations for these areas are Pheasant Tail Grass with the sky blue flowers of Russian sage. his grass is extremely drought tolerant once established. Giant Feather grass looks great with the purple flowers of penstemon ‘Midnight’. If you like blue foliage, try Elijah Blue fescue grass with Amazing Red flax for a show stopping combination.

Caring for grasses is easy. As a rule of thumb, if it browns in winter then cut it back before new growth starts. If it’s evergreen by nature just clean up outside leaves. Most like well drained soil and are tolerant of a wide range of garden conditions. You shouldn’t fertilize heavily because an excess of nitrogen can lead to lush, soft growth that tends to flop. Mulching with 2 inches of compost yearly will keep the soil and your plants in good shape. Water grasses regularly during their first year to help get a good root system established. Even grasses that are normally touted as drought-tolerant require a season or two to become fully established.

These are just a few of the places where grasses can enhance and add beauty to your garden. Fall is the perfect time to plant a new one.

Ornamental Grasses & Grass-like Plants

Lomandra ‘Platinum Beauty’ with convolvulus trailing over side.

Looking for plants that require minimal care, only occasional grooming, just enough water to meet their needs and are deer resistant? Plants that add beauty, movement and sound to your garden? You may already have some ornamental grasses and grass-like plants but this is a good time to add a little more pizazz and beauty to your landscape.

Diseases and insect pests are rarely found on grasses They have succeeded because of their adaptability and have evolved to suit almost every environment and climate on earth. True grasses generally have extensive root systems which help control erosion. Grass-like plants such as lomandra, dianella, cordyline, carex, restio, phormium, Japanese Forest grasss and liriope are some of the best companions for interplanting with grasses. A garden just isn’t complete without the architectural qualities they provide.

Pheasant Tail Grass

There’s a reason old favorites like Karl Foerster feather reed grass is so popular in landscapes. It doesn’t get too tall or overpowering in the smaller garden and its upright habit is neat and tidy. Pheasant Tail grass is another popular grass that is carefree and long-lived. It grows to only 3 by 3 feet, is not fussy about soil and looks good anywhere you plant it. It combines beautifully with the sky blue flowers of Russian sage and is extremely drought tolerant once established.

I like variegated plants and two-tone grasses combine well with many other garden plants. Miscanthus sinensis ‘Morning Light’ is an especially refined and elegant ornamental grass. Fine leaf blades are green with clean, paper-thin, white margins that give the plant a silvery cast when viewed from a distance. It is luminous when backlit by the early morning or late afternoon sun. Morning Light tends to keep its upright shape better than some other cultivars and rarely flops. The reddish bronze plumes that appear in late fall are spectacular.

Libertia – a grass-like plant

A grass-like plant that I think should be used more often in gardens in libertia. Narrow, rigidly straight leaves form compact clumps that are especially useful i poolside, accent planting and thrive as well in containers. They require only moderate watering and can add a warm punch of color,

Another plant that is finding a place in the low maintenance garden is dianella. With 18 inch clumps of soft blue leaves, light blue flowers with lavender-purple fruits dianella cerulean ‘Cassa Blue’ is just one of this group of perennial flax lily that makes a great addition to the garden. Dianella intermedia grows fast with whitish blossoms during the summer months. The berries which follow are deep purple-blue and highly ornamental They can be especially attractive filling a shady nook though this plant can thrive in either su or shade.
