Every year as we enter the fall season, I realize how much I admire ornamental grasses and their feather-like textures, billowing silhouettes, and delicate seed heads. They add a nice contrast to woody and herbaceous perennials, which improves the intrigue and flow of your space. Although, ornamental grasses are great for adding year-round interest, fall is their time to shine! This is when their flower plumes (technically called inflorescences) reach their peak bloom making the plants glisten with ethereal beauty, especially when backlit by the morning or afternoon sun. Once winter arrives, these grasses continue to provide perpetual interest, as well as revive a sense of inspiration during a season of dormancy.
However, finding just the right grass can be intimidating, as there are so many great options to choose from. Below are 5 fantastic ornamental grasses for fall in southeastern United States.
