Choosing native plants when designing new gardens is becoming increasingly popular. Some of the benefits of using native plants include reduced use of chemicals, improvement of the soil, erosion and flood control, and increased habitat for birds and butterflies.
The four plant communities that existed in the Chicago area in pre-settlement times were woodland, wetland, savanna and prairie. Each of these communities evolved on the various clay soils left by glaciers. As a result, many of the native plants adapted to alkaline clay soil.

Many of these plants also have extensive root systems that extend deep into the soil. Roots naturally amend the soil with organic matter as old root cells fall off and transform impervious clay into spongy, rich black soil.
Deep loamy soil has excellent drainage that allows any precipitation to soak through the soil, filter through it, and fill aquifers and wetlands with clean ground water.
By choosing native plants for your landscape, you contribute to the restoration of the natural ground water hydrology and give rainwater a place to filter in the place where it falls. A bed of natives located in a rain garden provides a place for water to soak into the soil rather than run off.
Once the extensive root systems of native plants are established, common weeds cannot compete for space in the soil. Butterflies and birds are attracted to the flowers and seed heads of native plants. And because these plants thrived before pesticides were invented, they can thrive in today's gardens without these sprays and powders.
While all these benefits are welcomed, the best reason to choose native plants is their beauty. Familiar favorites include the purple coneflower, black-eyed Susan, bee balm, and butterfly weed. There are many more to consider.
