Ornamental grasses are becoming increasingly popular for use in water-wise landscape designs. Combined with drought tolerant perennials, ornamental grasses can create a strong visual impact from summer through the winter season.
Note that not all ornamental grasses are water-wise and that some species will not survive in all US regions. Also keep in mind that some ornamental grasses can be invasive, especially those that spread by rhizomes or have unusually high seed germination.
Consult reputable local plant nurseries and Cooperative Extension Service offices for more information about drought tolerant ornamental grasses adapted to your area.
