Hydrangea macrophylla 'Onyx Flamingo'

Hydrangea macrophylla 'Onyx Flamingo' is a striking deciduous shrub prized for its voluminous baby-pink mophead blooms and distinctive charcoal-black stems. This compact variety reaches 3–4 feet in height and width, making it ideal for garden beds and container planting. The rounded, serrated dark green foliage creates an elegant contrast to the delicate pink flowers. Bloom colour is pH-responsive—acidic soils encourage blue tones, while alkaline conditions maintain the soft pink hue. Plant in full sun to partial shade within rich, well-drained soil. Maintain consistent moisture, particularly in sunnier spots. Amend with aluminum sulfate to deepen blue colouring or add lime to intensify pink blooms. A versatile choice for any landscape.
