Annabelle Hydrangea

Annabelle Hydrangea is a classic smooth hydrangea prized for its enormous, rounded clusters of creamy white flowers. The blooms emerge with a soft green tint, mature to bright white, and often fade back to green as they age. This gradual color change provides a long season of interest from early summer into fall.

Its large flower heads brighten shaded borders, woodland gardens, foundation plantings, mixed shrub beds, and informal flowering hedges. Annabelle also works well in mass plantings, where several shrubs can create an especially impressive summer display. Give each plant enough room to reach its mature width so air can move freely through the foliage.

The blooms make excellent fresh-cut flowers, and the dried flower heads can be enjoyed in arrangements long after the growing season ends. Because the flowers may become heavy after rain, proper spacing and support from nearby shrubs can help keep the stems looking tidy. Avoid planting Annabelle where the branches will lean across a walkway or become crowded by larger plants.

Plant Annabelle Hydrangea in morning sun to part shade with moist, well-drained soil. In Georgia, protection from intense afternoon sunlight can help reduce wilting and leaf stress during hot summer weather. Water deeply and regularly during its first growing season. A two- to three-inch layer of mulch can help the soil retain moisture and keep the root zone cooler.

Annabelle Hydrangea blooms on new wood, so it can be pruned in late winter or early spring before fresh growth begins. Remove dead, weak, damaged, or crossing stems first, then shorten the remaining branches if shaping is needed. Our Old Wood vs. New Wood Hydrangeas guide explains why knowing a hydrangea’s blooming habit is important before pruning.

The University of Georgia Extension guide to pruning hydrangeas provides additional information about smooth hydrangeas such as Annabelle and confirms that they flower on new growth.

With morning sun, regular moisture, proper spacing, and sensible pruning, Annabelle Hydrangea can provide dependable white flowers and attractive seasonal interest for many years.
