Technically Gardens of Babylon is not part of the Nashville Farmer's Market, but I love it so much that I had to give it a shout out all by itself.  It is a full blown garden center right in the middle of the Farmer's Market.  They have a huge greenhouse that has a fabulous selection of everything from vegetables to fiddle leaf figs.  In fact, this is where Steve and I get the majority of our vegetables for the garden.  The staff is so knowledgeable and for my local friends they also have a landscape company that does everything from design and instillation to outdoor kitchens and personal farming.
