Groundcovers, vines, and ornamental grasses can be important elements in a
landscape. Groundcovers may be evergreen or deciduous, certain low-growing
shrubs make excellent groundcovers such as Cotoneaster, Grow-low sumac,
Emerald Spreader yew, and Blue Pacific juniper, to name a few. Many perennials
have a ground cover habit. Dianthus, Lamium, Lamb's Ear, Creeping Jenny,
and Ajuga are some that have interesting foliage. The best evergreen groundcovers
are Pachysandra, Ivy, and Vinca minor, all of which prefer some shade.
Vines may be used vertically or horizontally. Most often they provide a vertical element and can be grown on arbors, trellises, trees, and walls. It is important to select the correct vine for each site.
Ornamental grasses can be very structural or can create a cloud-like effect, depending on the variety used. They are most effective when planted in mass. There are several varieties of grasses that are perennial, and there are some treated as an annual ornamental grass in the Middle Tennessee area, such as red fountain grass (Pennisetum rubrum).
