Why Choose Perennials?

• Long-Lasting Impact: Perennials establish strong root systems and reappear each season with minimal effort.
• Diverse Blooms: Expect a range of flower shapes, colours, and fragrances that evolve throughout the growing year.
• Sustainable Gardening: These plants require less replanting than annuals, making them eco-friendly choices for any garden.

Planting & Care Guide

• Planting Time: Best planted between early spring and early autumn when soil is workable.
• Soil Preferences: Most perennials thrive in well-drained, fertile soil with moderate moisture. Amend heavy clay with compost if needed.
• Sun Requirements: The majority prefer full sun to partial shade—refer to the plant label for specific needs once received.
• Caring Tips: Water regularly during dry spells until established. Mulch in spring to retain moisture and suppress weeds. Deadhead spent blooms to encourage further flowering.
• Mature Size & Spacing: Varies by species; expect heights between 20–80cm. Space plants according to their mature spread (usually 20–40cm apart).
• Pruning: Most varieties benefit from cutting back dead growth in late autumn or early spring.
