8 Spectacular Grasses to Energize a Fall Garden

It's hard to beat what ornamental grasses have to offer: incredible texture, sublime colors and seed heads that sway and provide movement in the garden. As autumn begins, these spectacular plants move out of the background to claim our attention in ways that other plants simply can't. With their wide range of sizes, forms and colorations, you are sure to find an ornamental grass that is suited to your outdoor space.

Muhly grass offers one of the most stunning colorations of all the ornamental grasses. It starts out as a neat green mound of fine foliage, and by summer's end it begins developing a mauve-pink spray of seed heads. This grass blends in beautifully with other ornamental grasses and flowering perennials.
