• Wildlife Benefits: Flowers attract bees, butterflies, and other pollinators.

• Hardiness: Fully hardy in the UK and Ireland.

Planting Conditions and Ideal Location

• Light Requirements: Prefers partial shade; can tolerate morning sun but benefits from protection from strong afternoon sun to prevent leaf scorch.

• Soil Preferences: Fertile, moisture-retentive but well-drained soil enriched with organic matter.

• pH Range:

  • Acidic soil (pH below 6) produces blue to purple flowers.

  • Alkaline soil (pH above 7) produces pink to red flowers.

• Moisture Needs: Consistently moist soil is essential, particularly in summer; avoid allowing the root zone to dry out.

• Planting Time: Best planted in spring or autumn when soil is warm and moist.

• Spacing: Space plants 1–1.5 metres apart to allow for mature spread.

• Shelter Needs: Plant in a sheltered spot, protected from strong winds and late frosts which can damage emerging flower buds.

• Companion Planting: Pairs beautifully with hostas, ferns, Japanese maples, and shade-loving perennials.

• Container Growing: Suitable for large pots; use a quality loam-based compost and water regularly.

Routine Care, Feeding, and Seasonal Maintenance

• Watering:

  • Water deeply once or twice weekly during dry periods.

  • Ensure soil remains consistently moist but not waterlogged.

• Feeding:

  • Apply a balanced slow-release fertiliser in spring.

  • For blue flowers, use a hydrangea colourant or aluminium sulphate in acidic soil.

  • For pink flowers, use lime to increase soil alkalinity if needed.

• Pruning:

  • Minimal pruning—remove only dead or damaged stems in late winter or early spring.

  • For older plants, cut out 1–2 of the oldest stems at the base to encourage new growth.

  • Leave faded flower heads on through winter to protect developing buds from frost; remove in spring.

• Mulching: Apply a 5–8 cm layer of organic mulch in spring to conserve moisture, improve soil, and suppress weeds.

• Pest and Disease Resistance: Generally resistant, but may occasionally suffer from aphids, leaf spot, or powdery mildew—improve airflow to prevent fungal issues.

• Winter Care: Fully hardy; in colder areas, mulch heavily around the base and cover with fleece during severe frost to protect buds.

• Weed Control: Keep the base area free of weeds to reduce competition for water and nutrients.

• Longevity: Long-lived shrub that, with proper care, will bloom reliably for decades.

• Size
  P23, 10-15 flwr.
