Ornamental grasses add nice touch

M.G. Gallagher

The colors, lusters, and forms of ornamental grasses are an interesting addition to any garden. In an area where the more subtle nature of our background colors is an important consideration in garden planning, grasses can be an important accent and feature.

The basic considerations for selecting ornamental grasses include size, form, color and aggressiveness. Light and water factors certainly are key.

Many ornamental grasses are not hardy here, but you will certainly find at least one variety in a local outlet that is for sale. That’s OK. Some ornamental grasses are annuals. Some perennial varieties that are not hardy here can be managed by container-planting outside, ground level in a hole, and then moving to a warmer location for the winter. Mulching can help pull borderline hardy plants through the cold in your particular microclimate. There are many grasses that are rated to zone 4, and some of them survive into Vail. There are also a few worthy ornamentals that are fine to zone 3.

Some ornamental grasses spread vigorously, some at a medium clip, and a few nice ones are not aggressive at all. Be sure to ask or research.

Blue fescue is among the best known ornamentals in the mountains and foothills. As a stand-alone specimen grass, it is very attractive, in fact it looks better by itself, with ample space between other ones when using more than one. It is available in some excellent named varieties. Ornamental green fescues are on the market, too.

Another nice feature of these ornamental fescues is that they are not fast spreaders; on the contrary. They are among the best behaved of the grasses and the varieties are on the compact side, usually 1-2 feet. While they need some moisture in hotter areas, they are not a particularly thirsty grass.
