Ornamental Grasses for Iowa
Ornamental grasses are becoming more popular as garden and landscaping plants, offering interesting textures not often found in other ornamental plants. Most of Iowa is well suited for growing grasses, having been originally covered with an inland sea of grasses, the waves formed by the wind.
Many of our native prairie grasses and woodland grasses are beautiful and can be used in the garden. Only a few native species are currently in use. The most easily purchased ornamental grasses are non-native, introduced species. Some of these introduced species are benign, while others have the potential to become invasive weeds. Amur silvergrass (Miscanthus sacchariflorus) is one species that has become invasive in Iowa.
This site has only information about members of the true grass family, Poaceae. Some plants that belong to other plant families look very much like grasses but will not be treated here. More ornamental grass species and cultivars will be added to this section of the Grasses of Iowa site over the next year.
