Woodland trails at Jenkins Arboretum

Celebrate the height of spring blooms with two full days devoted to the artistry of garden design. At Chanticleer—often called the most beautiful garden in America—discover a living masterpiece of horticultural imagination, where each area reveals inventive plant combinations, bold color, and an unmistakable sense of joy. Continue to Stoneleigh: A Natural Garden, where a former Gilded Age estate has been reimagined as a sanctuary of native plants, historic trees, and graceful stonework that honors the landscape’s past while embracing its ecological future. Also visit Jenkins Arboretum a serene, 48-acre oasis where native plants, woodland trails, and seasonal blooms create a vibrant sanctuary for nature lovers and garden enthusiasts alike.

The tour, led by horticulturist Chelsea Mahaffey, also includes visits to three private gardens opened exclusively for Smithsonian Associates. Each reflects the creativity, dedication, and distinctive vision of its owner—ranging from meticulously curated plant collections to artful outdoor living spaces that seamlessly blend design and nature. Touring these hidden gems offers a rare opportunity to engage directly with the gardeners who shape them, discover new ideas for your own landscape, and experience firsthand the intimate beauty and inspiration found in some of America’s finest private gardens.
