Grasses With Gusto

Ornamental Grasses lend a unique dimension to any landscape with their texture, sound, motion, and architecture. By planting ornamental grasses, you can also add multi-seasonal excitement to your landscape. Whether combined with other ornamental plants or featured by themselves in “Grass Gardens,” ornamental grasses are attractive from spring until late fall, and often even through winter.

Choosing Ornamental Grasses

It can be challenging to select the best ornamental grasses for your landscape. Varieties may be short or tall, and upright or weeping. Foliage can be bold or fine and comes in colors ranging from green, blue-green, lime-green, gold, and red, to variegated with horizontal or vertical bands of white or yellow. Flower heads can be showy plumes, fuzzy foxtails, or airy particles, and appear from mid-summer to fall, depending on variety. Dried flowers and leaves may persist into winter, looking particularly effective against a snowy backdrop.

Depending on the conditions of your landscape and your grass preferences, there are many different types of grasses to try.

Screens Or Barriers

Taller growing varieties such as Silver Arrow Grass (Miscanthus sinesis) or Feather Reed Grass (Calamagrostis) can be used as effective screens or windbreaks. The wind rushing through their foliage creates added sensations of sound and movement. Even some of the medium-sized growers, such as varieties of Miscanthus sinensis, can enclose a patio or act as a barrier against wind, noise, or an undesirable view.

Specimens

Many ornamental grasses also make excellent specimen plants and can turn a dull corner into a focal point of color and texture. Some of the most dramatic grasses for specimen planting include Maiden Grass (Miscanthus sinensis gracillimus) with its graceful arching vase shaped foliage and pinkish blooms which age to cream, and Porcupine Grass (Miscanthus sinensis ‘Strictus’), which has upright green and yellow banded stems.

Waterscaping

Water gardens and ornamental grasses go together beautifully. A grouping of grasses looks particularly effective at the water’s edge, softening the boundary between land and water. Many grasses such as Miscanthus can tolerate moist conditions, and some, like sweet flag (Acorus) and Variegated Reed Grass (Calamagrostis acutiflora ‘Overdam’), can grow in shallow water. Sedges (Carex), which are not true grasses but are similar in appearance, are also moisture-tolerant. Look for varieties with plain, variegated, or golden foliage.

Groundcovers

Grasses that are groundcover varieties spread by underground stolons rather than forming tight clumps. One such selection is Ribbon Grass (Phalaris arundinacea ‘Picta’), a fast-spreading green-and-white variegated variety, particularly useful as a groundcover in difficult areas such as slopes or even under trees that cast light shade. Give this one plenty of space! You’ll also want to try green or variegated Liriope and  Mondo Grass (Ophiopogon).

Beds and Borders

Massed in groups, ornamental grasses are wonderful as a background to, or in combination with, other plantings. Try planting them with perennials such as Black-eyed Susan, Sedum ‘Autumn Joy’, and Veronica ‘Goodness Grows’ or ‘Sunny Border Blue’ for a dynamic summer and fall interest addition to your landscape. Varieties for mass planting include Switch Grass (Panicum virgatum), which has upright delicate flowers and leaves that turn reddish in the fall; Korean Feather Reed Grass (Calamagrostis acutifolia ‘Stricta’) which yields stunning buff-colored plumes over a long period; and Fountain Grass (Pennisetum alopecuroides) that sports maroon foxtails, which age to cream in late fall. A number of different forms of Fountain Grass are available: ‘Hameln’ is a dwarf variety with creamy foxtails, while ‘Moudry’ has unusual black flowers. For edging beds and borders, plant low-growing Blue Fescue (Festuca glauca). Its steely blue clumps hold their color through winter and contrast well with pink or purple flowers or foliage.

Growing Grasses

Ornamental grasses are relatively easy to grow. A site that receives at least six hours of sun per day is best, although varieties like variegated Miscanthus (Miscanthus sinensis ‘Variegatus’) can grow well in as little as four hours of sun. Soil preparation, as with everything you plant, is a must, so work in plenty of organic matter such as peat moss or Leafgro. Fertilize in early spring with Espoma 5-10-5 or any all purpose fertilizer, when new growth is starting to show. Clumps should be cut back to within 6″ of the ground at this time, and can be divided if needed.

You’ll love the look ornamental grasses can give your landscape, and these easy-care plants can be effective at many functions in many different types of landscapes. Give them a try today!
