There are many important reasons why you should be interested in having a rain garden. Rain carries pollutants like oil, chemicals, pesticides, and sediments into storm drains and ultimately into streams and rivers. A rain garden utilizes bioretention, where plants and soil remove these pollutants from storm water. Traditionally, curbs, gutters, and storm drains are used to carry runoff directly into streams and rivers without bioretention filtering. Rain gardens are built in low-lying areas using layers of soil, sand, and organic mulch that filter the rain. This soil absorbs and stores the rainwater and nourishes the trees, grasses, and other native plants. Thus, the rain garden filters and reuses the water reducing storm water pollution and providing attractive landscaping.

A rain garden is a shallow landscape depression incorporated into an existing landscape to treat storm water runoff  mainly  from roofs but also from driveways and patios.   A rain garden is designed to merge two important goals:  aesthetics and water quality.

Rain gardens look like regular flower gardens  and by using native plants, the design is natural and   is  a habitat to support birds and butterflies.  In addition to using native plant species in your rain garden, this is  an excellent way to increase native plants.
