USEPA Great Lakes Ecosystems - Green Landscaping: Greenacres Index Page

Landscaping with native wildflowers and grasses improves the environment. Natural landscaping brings a taste of wilderness to urban, suburban, and corporate settings by attracting a variety of birds, butterflies and other animals. Once established, native plants do not need fertilizers, herbicides, pesticides or watering, thus benefiting the environment and reducing maintenance costs. Gardeners and admirers enjoy the variety of colors, shapes, and seasonal beauty of these plants
