Native to the Eastern United States, Hydrangea arborescens (Smooth Hydrangea) is acclaimed for its large, showy snow balls that brighten shady areas and bring life to the garden from mid to late summer. Blooming for weeks, it generally offers a spectacular color show starting with lime-green pom-poms in late spring, changing from cream to brilliant white for weeks, then back to pale green in late summer before switching to a tan shade in the fall. Pink cultivars are now becoming available, such as 'Invicibelle Spirit', which features dark pink buds opening to hot pink flowers which then turn soft pink as they mature, finally changing to green at the end of their life cycle.

  • Since Smooth Hydrangea blooms on new wood, pruning has to happen late winter or early spring to encourage vigorous growth. The harder you prune (even to the ground), the larger the flowerheads will be.
