Hydrangea macrophylla 'Big Daddy'

Mophead Hydrangea

Hydrangea macrophylla 'Big Daddy' — commonly called Big Daddy bigleaf hydrangea — is a deciduous shrub known for its exceptionally large mophead flower clusters that bloom in shades of pink, lavender, or blue depending on soil pH. The oversized rounded blooms appear through summer above broad glossy green foliage, creating a bold ornamental presence in shaded landscapes. It is especially valued for abundant flowering and large flower size.

Mature Size:
Width: 5–6 ft
Height: 5–6 ft

USDA Zones: 6a–9b

Form: Rounded, vigorous shrub

Light: Partial shade to morning sun with afternoon shade

Soil / Water: Moist, well-drained, fertile soil; prefers consistent moisture and organic-rich conditions

Features / Wildlife / Landscape Uses:
Large flower heads provide strong summer color in foundation plantings, woodland borders, cottage gardens, and mixed shrub beds. Flowers attract pollinating insects and are excellent for fresh or dried arrangements. Broad foliage gives the plant a lush appearance throughout the growing season.

Care:
Prune lightly after flowering if needed, since flower buds form on old wood. Protect buds from late spring frost in colder climates for best bloom performance.
