Our Garden & Horticulture

Our Garden has grown from humble beginnings as a WPA project to an 155-acre garden filled with thousands of plants. More than forty themed gardens are spread across site. Some gardens focus on a single plant (camellias, hydrangeas, roses), others look at a plant from a specific region (Japan, Virginia), while others provide homeowners with great ideas and or new plants to use in their own garden.
