The Sunny Garden is located at Bon Air Park, Wilson Blvd. at North Lexington Street between Ballston and Seven Corners. The Garden is at the north end of the parking lot.

Created in 1990, the Sunny Garden displays a great number of perennials, most for sunny locations and, under the canopy of the white oak, shade-tolerant plants and late winter to early spring bloomers. The Garden offers four season interest with its variety of flowering plants and grasses. Over the years, it has developed and expanded to meet changing conditions and its beds now incorporate more native plants.
To learn more about the creation and evolution of the Garden and to see pictures of Master Gardeners at work on some of the multi-year (2013–2017) renovation projects, read Sunny Demonstration Garden at Bon Air Park, Sunny Garden Renovations 2014, New Focal Point for the Sunny Garden, and Sunny Garden Leaves No Stones Unturned. In 2020, a new large compost system was installed to show how garden waste can be ecologically repurposed. Most recently, the Garden was expanded to include an area featuring native shrubs.
