Lupin Legendary Blue 2ltr

Lupin ‘Legendary Blue’ is a real showpiece perennial, producing tall, stately spires packed with rich blue pea-like flowers, often with crisp contrasting tips, rising above a bold clump of fresh green, palmate foliage. It’s perfect for adding that classic cottage-garden drama in early summer, and it looks fantastic planted in groups through mixed borders. As a bonus, lupins are brilliant for pollinators, bringing bees and butterflies into the garden, and the flower spikes also make excellent cut stems for a vase.

Lupins are nitrogen-fixing plants (they can help improve soil health over time), and with regular deadheading they often give a second flush of flowers later in the season. They’re a great choice for Avon Bulbs & Plants customers who want big colour, height and impact—without needing complicated care.

Planting Instructions

When to Plant:

Plant in spring or autumn, while the soil is moist and workable. Container-grown plants can be planted most of the year, avoiding periods when the ground is frozen or waterlogged.

Where to Plant:
Choose a position in full sun (best flowering) or light/partial shade with well-drained soil. Lupins prefer soil that is not waterlogged in winter. Ideal for mixed borders, cottage gardens, and cutting gardens.

How to Plant:

• Depth: Plant so the top of the rootball is level with the soil surface.
• Spacing: Space 45–60 cm (18–24 inches) apart to allow good airflow and sturdy growth.
• Soil Prep: Improve the planting hole with a little garden compost if soil is very light, but avoid over-feeding as it can encourage leafy growth at the expense of flowers.

Watering:
Water well after planting. Keep the soil evenly moist while the plant establishes. Once settled, water during prolonged dry spells, especially when in bud and flower.

Aftercare Tips:

• Deadhead flower spikes as they fade to encourage a second flush and to stop the plant putting energy into seed.
• In exposed areas, use a discreet stake if needed as stems get taller.
• Cut back finished flower stems to a strong leaf in summer; in autumn, tidy up as foliage fades.
• Watch for slugs and snails on young shoots in spring.

Top Tip:
Lupins look best planted in groups and partnered with classics like delphiniums, roses, foxgloves and ornamental grasses. For longer flowering, keep deadheading and give a deep water during dry spells.
