Rain Gardens: Why You’ll Want One


What do you think of when you hear the words “rain garden?” If you answered, “sparkling pools and lush vegetation,” you’re partly right.

But the beauty behind these verdant islands of native plants and grasses goes much deeper. To understand why, it helps to know a little about storm water runoff.

As rain makes its way across lawns, roofs, parking lots and streets, it picks up chemicals such as fertilizers, motor oil, pesticides, herbicides, bacteria and other contaminants. These end up in streams, rivers and eventually the Gulf of Mexico.

Runoff can even affect the temperature of those waterways. All of these things together can harm water-dwelling organisms, the animals that feed on those organisms and so on.

Rain gardens can help prevent all that and more. Plus they’re extremely drought tolerant and provide perfect habitat for native birds and pollinators.

So are you ready to help prevent water pollution and increase your garden enjoyment? To learn how to select plants for and create your own epic rain garden, visit
