Hydrangea arborescens 'Dardom'

White Dome Hydrangea

Hydrangea arborescens 'Dardom' — commonly sold as White Dome® hydrangea — is a deciduous flowering shrub valued for its broad lacecap-style white blooms that create a softer, more natural look than traditional mophead hydrangeas. Large flattened flower clusters are made up of tiny fertile flowers surrounded by larger white sterile florets, blooming in early to midsummer above sturdy upright stems. Its dark green foliage and strong branching give it excellent structure in the landscape. 🌿🤍

Type: Deciduous shrub

Mature Size:
Width: 4–5 ft
Height: 4–5 ft

USDA Zones: 3a–8b

Form: Upright, rounded shrub

Light: Partial shade to full sun

Soil / Water: Moist, well-drained soil; prefers even moisture but tolerates average garden conditions once established

Features / Wildlife / Landscape Uses:
Flat white blooms attract bees, butterflies, and other pollinating insects. Strong stems usually hold flowers upright better than many smooth hydrangeas. Excellent for woodland gardens, native borders, naturalized areas, and mixed shrub plantings.

Care:
Prune lightly in late winter or early spring if shaping is needed, since flowers form on new wood. Remove older stems periodically to encourage vigorous growth
