Plant Care & Growing Guide

• Soil: Prefers fertile, well-drained soil. Improve clay or sandy soils with compost before planting.
• Light: Best performance in full sun or light shade. Avoid deep shade for optimal flowering.
• Watering: Water regularly during establishment. Once mature, most perennials are drought-tolerant but benefit from watering in dry spells.
• Feeding: Apply a balanced fertiliser in spring to encourage healthy growth and abundant blooms.
• Pruning: Deadhead spent flowers to prolong blooming. Cut back foliage in late autumn or early spring before new growth emerges.

Design Ideas & Companion Planting

• Create layered borders by combining with low-growing groundcovers at the front and taller shrubs or grasses at the back.
• Pair with classic cottage garden favourites such as Salvia, Nepeta, or Geraniums for harmonious colour schemes.
• Add ornamental grasses or evergreen shrubs nearby for year-round structure and interest.
