This formal garden was built to honor those who have served on the Garden's Board of Trustees. The stairway leading down to the Sterne Gazebo was given in memory of Augustus H. Sterne, a founding trustee. The back wall of the garden is planted with Evergreen Clematis, Clematis armandii, which blooms profusely in early spring and perfumes the garden. Plantings in the Trustees Garden were updated in 2012 and now feature blue and white Hydrangeas, Hibiscus syriacus and flowering perennials. The garden was also updated in 2015 during the renovation of the neighboring Lou Glenn Children's Garden.
