Leucojum aestivum Gravetye Giant

A magnificent, larger-flowered selection of the much-loved Summer Snowflake, Leucojum aestivum 'Gravetye Giant' produces elegant clusters of nodding, pure white, bell-shaped flowers, each delicately tipped with emerald green. Taller, more vigorous and more floriferous than the species, it creates a breathtaking display in the late spring garden.

This outstanding cultivar was discovered in the famous gardens of Gravetye Manor in Sussex, the former home of the legendary gardener and writer William Robinson, whose pioneering ideas helped shape the naturalistic gardening style we know today. Fittingly, 'Gravetye Giant' excels when planted in generous drifts, where its graceful flowers appear to float above lush green foliage.

Each sturdy stem carries up to eight large, gently scented bells that sway gracefully in the breeze. Flowering in April and May, it thrives in moisture-retentive soils and is particularly at home beside ponds, streams, woodland edges or beneath deciduous trees, where it naturalises steadily to form impressive colonies.

Awarded the RHS Award of Garden Merit, this long-lived bulb combines beautifully with Camassias, Primulas, ferns, Narcissus and other moisture-loving spring plants, bringing elegance and movement to both formal and informal gardens.

A superb heritage selection that offers exceptional vigour, timeless beauty and effortless naturalising.

Planting Instructions

When to Plant:

Plant Leucojum bulbs in autumn, from September to November, while the soil is still workable and before winter frosts arrive.

Where to Plant:
Choose a position in full sun or partial shade with moist, fertile, well-drained but moisture-retentive soil. 'Gravetye Giant' thrives beside ponds, streams, damp borders, woodland gardens and beneath deciduous trees.

How to Plant:

• Depth: Plant bulbs approximately 10–15 cm (4–6 inches) deep.
• Spacing: Space bulbs about 10–15 cm (4–6 inches) apart.
• Soil Prep: Enrich the soil with compost or well-rotted organic matter before planting to retain moisture while maintaining good drainage.

Watering:
Water thoroughly after planting to settle the soil. Keep the soil consistently moist during active growth, particularly during dry springs.

Aftercare Tips:

• Allow the foliage to die back naturally after flowering to replenish the bulbs.
• Leave established clumps undisturbed, as they will gradually increase in size each year.
• Apply a mulch of compost or leaf mould each autumn to conserve moisture and improve soil fertility.

Top Tip:
Plant in generous drifts beside ponds or beneath deciduous trees where the taller flower stems can naturalise into spectacular colonies, just as William Robinson intended at Gravetye Manor.
