Gardens of Babylon, Nashville

Even if you've never been to Gardens of Babylon, you've probably seen some of their work—their landscape and design team was commissioned for projects at high-profile locations including Vanderbilt University and the Bicentennial Mall. It's no surprise then that the company also has a formidable garden center, an 18,000 square-foot space where people can use Inspiration Stations and consult with staff at demo areas to glean ideas for their own landscaping projects. The entire inventory is devoted to sustainable landscaping, and includes only all-natural, non-toxic, organic, and non-GMO supplies, as well as eco-conscious elements such as rain barrels.
