What is a Rain Garden?

RainGardenDrawingedited.jpg

A rain garden is simply a garden designed to collect and filter rainwater running off of driveways, rooftops, or streets. Rain gardens are planted with perennials and grasses that can withstand both wet and dry conditions .Rain gardens can take many shapes and sizes. Plants can be neatly manicured or more “wild” and “natural” looking. A rain garden adds beauty to your yard while also helping the natural environment.

Why Plant a Rain Garden?

Rainwater that falls onto roofs, roads or driveways cannot pass through these impermeable surfaces to soak into the ground as it would in a natural system. Instead this water becomes polluted as it picks up trash, nutrients, sediments and bacteria and rushes into storm drains which lead directly into rivers and lakes. A rain garden catches polluted runoff, filters it, and allows the clean water to soak back into the ground. This keeps pollution out of our local rivers and replenishes ground water levels. Rain gardens also add beauty to a yard and create habitat for wildlife. Learn how to build a rain garden on your own property.
