Add Lasting Elegance to Your Garden with Hydrangea arborescens 'Strong Annabelle'

The Hydrangea arborescens 'Strong Annabelle' is a standout deciduous shrub prized for its enormous, rounded heads of pure white florets. As a robust improvement on the classic 'Annabelle', this variety features stronger stems that keep blooms upright—even in exposed garden spots—ensuring a spectacular display from midsummer into early autumn.

Why Choose 'Strong Annabelle'?

• Breathtaking Blooms: Enjoy large, showy flower heads from July to September—perfect for brightening shaded borders or woodland settings.
• Reliable Structure: Unlike many hydrangeas, 'Strong Annabelle' maintains its shape and rarely flops, even after heavy rain.
• Mature Size: Grows up to 150cm (59in) tall and wide, making it an impressive focal point or mass planting option.

Growing Guide & Care Instructions

• Sun/Shade: Plant in full sun or semi-shade for best flowering performance.
• Soil: Prefers non-alkaline, fertile, moist but well-drained soil. Avoid chalky soils to prevent yellowing leaves.
• Watering: Keep soil consistently moist, especially during dry spells in the first season after planting.
• Pruning: Cut back stems in late winter or early spring to encourage strong new growth and bigger blooms.
• Feeding: Apply a balanced fertiliser in spring as new growth emerges.

Planting & Design Tips

• 'Strong Annabelle' excels as a specimen shrub or grouped en masse for dramatic effect.
• Create a woodland-style border by pairing with ferns, hostas, or shade-loving perennials.
• Add to mixed borders for a long season of interest—combine with astilbes or Japanese anemones for layered texture.
