Hydrangea Mac. Glowing Ember

Glowing Ember Hydrangea

Hydrangea macrophylla 'Glowing Embers' — commonly called Glowing Embers bigleaf hydrangea — is a deciduous flowering shrub prized for its rich mophead blooms that shift from deep rose-red to reddish-purple depending on soil pH. In alkaline soils the flowers develop stronger red tones, while more acidic soils can deepen them toward purple. Large rounded flower heads bloom in summer against glossy dark green foliage, creating bold contrast in shaded garden settings. 

Type: Deciduous shrub

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

USDA Zones: 6a–9b

Form: Rounded, dense shrub

Light: Partial shade to morning sun with afternoon shade

Soil / Water: Moist, well-drained, rich soil; prefers consistent moisture and benefits from mulch in summer

Features / Wildlife / Landscape Uses:
Bold flower color provides strong midsummer interest in foundation plantings, cottage gardens, woodland borders, and containers. Flowers attract pollinating insects and are useful for fresh or dried arrangements. Glossy foliage adds a lush texture through the growing season.

Care:
Prune only immediately after flowering if needed, since flower buds form on old wood. Protect flower buds in colder climates and avoid severe spring pruning.
