Against a backdrop of gently swaying tall Grasses, this garden recreates the look of a prairie wildflower meadow. Make sure you have enough room for the Erianthus Grass--it gets huge! If space is limited, you may want to use Calamagrostis 'Karl Foerster' in its place. Give this garden a full day's sun and average soil. Before planting, clear the area of existing grass or weeds. After you have installed the perennials, sow seeds of a nonagressive Grass, such as Little Bluestem, between them. These will grow into tufts of pretty meadow Grass, lending even more of a naturalistic look while helping to suppress weeds. Just a late-winter cutting of the dried Grasses and stalks is all the maintenance you'll need to do. Since all of these wildflowers are from sturdy stock, they'll need supplemental watering only during periods of drought. From midsummer through fall, this little piece of prairie will sing with color.
