Annabelle Hydrangea (Hydrangea arborescens ‘Annabelle’)

Annabelle Hydrangea is one of the most popular and reliable flowering shrubs for Canadian gardens, prized for its enormous snowball-like white blooms and exceptional cold hardiness. This Hydrangea arborescens variety produces spectacular flower heads that can reach up to 30 cm (12 inches) across, creating a dramatic display from early summer through late summer.

This deciduous shrub forms a rounded, multi-stemmed habit with lush green foliage that provides season-long interest. The blooms emerge soft green before maturing to brilliant white and eventually aging to attractive pale green tones later in the season. Unlike some hydrangea varieties, Annabelle blooms on new wood, meaning it flowers reliably every year even after harsh winters or spring pruning.

Annabelle Hydrangea thrives in full sun to part shade and prefers consistently moist, well-draining soil. Its adaptability, long bloom period, and dependable performance make it an excellent choice for foundation plantings, mixed shrub borders, cottage gardens, and mass landscape plantings. The large blooms are also highly valued for fresh and dried floral arrangements.
