Growing Guide: Simple Care for Spectacular Results

• Planting Time: Best planted in spring or autumn while dormant. Bare roots establish quickly in well-drained soil.
• Sun/Shade Requirements: Prefers full sun or partial shade. Choose a sheltered spot to protect from strong winds.
• Soil Preferences: Grows best in fertile, well-drained soil with neutral to slightly acidic pH (6.0–7.0).
• Watering & Feeding: Water regularly during dry spells. Apply a balanced fertiliser in spring and after the first flush of flowers.
• Hardiness: Fully hardy in most UK regions (USDA zones 6-9). Mulch in winter for extra protection in colder areas.

Planting & Care Tips

• Dormant bare roots should be soaked before planting.
• Space plants about 30cm apart to allow clumps to develop.
• No need for complex pruning—simply remove spent stems at ground level after flowering finishes.
• Add organic mulch each spring to conserve moisture and suppress weeds.

Design Ideas & Companions

• Borders & Beds: Combine with Salvia, Rudbeckia, or Coreopsis for a prolonged season of colour.
• Pots & Containers: Mix with ornamental grasses or trailing Lobelia for striking displays on patios and balconies.
• Cottage Gardens: Plant alongside roses or lavender for classic summer charm.
