Description
Neat, hardy, and wonderfully floriferous, Hydrangea ‘Polestar’ is a compact paniculata that’s ideal for smaller gardens and patio pots. It flowers generously with cone-shaped blooms that open fresh white, often with a hint of lime, then gently blush towards soft pink as the season progresses.
Because it stays more manageable than many paniculatas, it’s perfect when you want that classic hydrangea look without needing loads of space.
Why you’ll love it
- Compact growth – brilliant for containers and front-of-border planting
- Long season of interest – flowers through summer into autumn
- Fresh, bright colour – white blooms maturing with soft pink tones
- Hardy & easy-care – reliable in Irish and UK gardens
Where to plant
Plant in sun to part shade in moist, well-drained soil. Great for:
- Patio pots and entrance containers
- Smaller borders and courtyard gardens
- Repeating in groups for a soft, flowering edge
Caragh Garden Notebook (care made simple)
- Light: Sun to part shade
- Soil: Moist, fertile, well-drained
- Water: Keep evenly moist, especially in pots
- Feeding: Feed in spring for strong growth and flowering
- Pruning: Prune in late winter/early spring—flowers form on new wood, so a tidy cut-back encourages lots of fresh stems and blooms
Style tip
Try it with lavender, nepeta, salvias, or ornamental grasses for an easy, long-season display that looks professionally planted.
