Description
For pure impact, Hydrangea ‘Polar Bear’ is a showstopper. It produces extra-large, cone-shaped flower heads that open a crisp creamy white, often with a hint of fresh lime, then soften into gentle blush tones as the season moves towards autumn.
It’s a hardy, reliable hydrangea with strong structure—brilliant for adding height, brightness and that “wow, what is that?” moment in borders and large pots.
Why you’ll love it
- Huge flower panicles – one of the most impressive paniculatas for size
- Long flowering season – summer through to autumn
- Hardy & easy-care – dependable in Irish and UK gardens
- Great for borders or big containers – instant structure and glow
Where to plant
‘Polar Bear’ thrives in sun to part shade in moist, well-drained soil. Ideal for:
- Back or middle of borders as a focal point
- Planting in groups for a soft flowering screen
- Large patio pots (keep watering consistent)
Caragh Garden Notebook (care made simple)
- Light: Sun to part shade
- Soil: Moist, fertile, well-drained
- Water: Water well during dry spells; don’t let container plants dry out
- Feeding: Feed in spring to support strong growth and blooms
- Pruning: Prune in late winter/early spring—flowers form on new wood, so a cut-back encourages strong new stems and big flowers
Style tip
Looks stunning with ornamental grasses, salvias, verbena bonariensis, and late-summer perennials—or planted against dark evergreens for maximum contrast.
