Annabelle hydrangea, also known as Hydrangea arborescens ‘Annabelle,’ is a perennial shrub known for its impressive, large white flower clusters that can brighten up any garden. Native to North America, Annabelle hydrangeas are popular among gardeners for their low maintenance care and stunning displays throughout the blooming season.
Characteristics of Annabelle Hydrangea
Description
The Annabelle hydrangea is a deciduous shrub that typically grows between 3 to 5 feet tall and can spread around the same width. Its rounded, mophead flower clusters can reach up to 12 inches across and are characterized by their stunning, pure white blooms that can sometimes take on a lime-green hue before maturing. In the fall, these blooms may transition to shades of tan, providing interest even outside of the peak blooming season.
Bloom Time
Annabelle hydrangeas bloom from late spring, typically beginning in June, and can continue blooming into the early fall. The sheer size of the flower heads not only makes a statement in any garden but also serves as an excellent addition to cut flower arrangements.

Annabelle hydrangeas thrive in USDA hardiness zones 3-9, which means they are adaptable to various climates and can prosper in both sunny and partially shaded locations.

Annabelle Hydrangea Care
Soil Requirements
These hydrangeas prefer well-draining soil with a slightly acidic to neutral pH (between 5.5 and 7.0). A soil mix containing organic matter, like compost, can enhance soil quality and provide necessary nutrients.
Watering
While the Annabelle hydrangea is relatively drought-tolerant once established, they thrive best with consistent moisture. It’s advisable to water them deeply but infrequently, allowing the soil to dry out slightly between watering sessions.
Sunlight
Annabelle hydrangeas adapt to a range of lighting conditions, thriving in full sun to partial shade. However, in hotter climates, providing some afternoon shade can help the plant avoid stress and prolong blooming.
| Watering Frequency | Sunlight Preference |
|---|---|
| Deep, once a week | Full sun to partial shade |
| Allow to dry slightly | Afternoon shade recommended |
Fertilizing
Fertilizing should take place in early spring before new growth starts. A balanced fertilizer with equal N-P-K (Nitrogen-Phosphorus-Potassium) ratios can help ensure vigorous growth and abundant blooms.
Pruning
Pruning is essential to maintain the shape of the Annabelle hydrangea and can be done in late winter or early spring. Deadheading spent blooms after they fade will encourage new growth and help maintain the plant’s aesthetics.
