Agapanthus Blue & White Collection

Transform your garden with the Agapanthus Blue & White Perennial Collection. This set includes 12 bare root plants featuring the dramatic blue 'Queen of the Ocean' and crisp white 'Polar Ice' varieties—both renowned for their tall stems and spectacular umbels of trumpet-shaped flowers.

Why Choose Agapanthus?

• Dramatic Impact: These perennials grow up to 1m tall, creating a bold, architectural statement in borders or containers.
• Reliable Summer Colour: Enjoy a profusion of blue and white blooms from July through September—perfect for injecting fresh colour during the warmest months.
• Long-Lasting Appeal: After flowering, the striking seed heads continue to provide structure and interest well into autumn.

Planting & Care Guide

• Planting Time: Best planted from late winter to early spring (February–April) while dormant.
• Location: Prefers full sun but tolerates light shade. Ideal for south or west-facing beds, borders, or large patio pots.
• Soil: Thrives in well-drained soil; amend heavy clay with grit or compost. Neutral to slightly acidic pH is preferred.
• Watering: Water regularly during establishment. Once mature, these plants are drought tolerant.
• Fertilising: Feed with a balanced fertiliser in spring as new growth emerges.
• Hardiness: Hardy in most parts of the UK (RHS H4); mulch in colder regions to protect roots over winter.
• Pruning: Remove spent flower stems after blooming. Leave seed heads for autumn interest or cut for dried arrangements.

Design Tips & Companion Plants

• Create bold swathes by planting en masse along borders or driveways.
• Makes a striking focal point in large patio containers—combine with ornamental grasses or lavender for contrasting textures.
• Pairs beautifully with perennials like Crocosmia, Salvia, and Rudbeckia that share similar sun and soil preferences.
