The Hydrangea Collection, developed with the assistance of the Atlanta Chapter of the American Hydrangea Society, is one of the finest in the Southeast. It contains more than 160 cultivars of Hydrangea macrophylla (both mophead and lacecap types), Hydrangea serrata cultivars (Mountain Hydrangea — a lacecap type from Japan), and our Native Hydrangea arborescens. These peak in late May and June, with stunning blooms of pink, blue and white.
At the same time, climbing hydrangeas (both native and Asian) can be seen in full bloom climbing the trees of the Southern Seasons Garden. July and August are filled with the blossoms of cultivars of Hydrangea paniculata, Hydrangea aspera and Hydrangea involucrata.
