This is smooth hydrangea ‘Annabelle’ (Hydrangea arborescens ‘Annabelle’).
‘Annabelle’ hydrangea is a cultivated selection of the native smooth hydrangea, which is a woody shrub that grows to 5' high by 5' wide or more, spreading slowly by suckers. It has dark green leaves that will turn a pleasant yellow in the fall some years and brown other years. The selection shown here has attractive white flower clusters up to 1' wide in contrast to the typical species, which has flat, much less showy flower clusters. It is hardy in USDA zones 3 to 9 and is widely available at nurseries since it is one of the most popular hydrangeas. You can see this smooth hydrangea growing in the Introductory Garden near the Administration Building..
