Uses for Ornamental Grasses
Ornamental grasses add an unusual flare in landscapes and gardens for different shapes, textures and movements in the design areas. Generally they should be cut back hard, in early spring to make room for the new growth to come, if the plant is a perennial and not an annual type.
When deciding how to use the prairie grasses as ornamentals, consideration needs to be given pertaining to how tall and wide the plants will get when full grown.
· Softening hard lines - Prairie grasses can be used to visually soften any hard lines in the landscape such as along driveways, mailboxes, edges, pools, etc.
· Privacy – Tall ornamental grasses can be used as privacy screens or to hide other unsightly areas in gardens, like a compost bin areas. Remember however, that they are not evergreen, so part of the year they won’t be hiding those areas.
· Ground Cover – Short varieties can make excellent ground cover by choking out weeds. This can be especially nice on very steep banks where it may be difficult to get other plants to grow. These will also help with erosion control.
· Container Gardens - Prairie grasses can also be excellent to use in container gardens, either in conjunction with other plants and flowers, or stand alone in cute planters. Its also a way to preserve annual grasses in some cases, by bringing them inside, or in a greenhouse over the winter.
· Border – The ornamental prairie grasses can make eye catching and functional edging or borders, around garden areas and flower beds. Plant a little closer than recommended for this application to make a nice, tight edge.
· Accents – Either the tall or short varieties can be used as accent plants in a bigger scope depending on your placement of the plants, and what you have growing around it. Give special attention to size, and coloring of the grass.
Ornamental prairie grasses are also wonderful to attract birds and other forms of wildlife to the garden. They provide seeds for the birds, grass blades for nests and some will nest right in the grass itself.
Grasses are easy to divide and may need to be divided every few years. Simply take a shovel and dig up the roots, fall is the best time to do this, cut the plant in half or quarters, and either give to a friend, or replant those divisions in other areas.
