Leucojum aestivum

Graceful, elegant and full of old-fashioned charm, Leucojum aestivum, commonly known as the Summer Snowflake, produces clusters of nodding, pure white, bell-shaped flowers delicately tipped with fresh green. Flowering in mid to late spring, it brings a refined beauty to borders, woodland gardens and damp areas where many other bulbs struggle.

Despite its common name, Summer Snowflake actually flowers in April and May, several weeks after the familiar Snowdrops, with which it is closely related. Each sturdy stem carries up to eight gently scented flowers that dance gracefully above rich green, strap-like foliage. Every petal is neatly marked with a tiny emerald-green spot at the tip, giving the flowers a beautifully finished appearance.

Native to meadows, riverbanks and damp woodland throughout Europe, Leucojum aestivum is particularly well suited to naturalising in moisture-retentive soils. It thrives around ponds, beside streams and beneath deciduous trees, where it gradually forms impressive colonies that return with increasing vigour each spring.

Awarded the RHS Award of Garden Merit, this long-lived, reliable bulb combines beautifully with Camassias, Narcissus, Primulas and ferns, bringing elegance and movement to both formal and naturalistic planting schemes.

A timeless perennial bulb that rewards gardeners with decades of effortless spring beauty.

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. Summer Snowflakes are particularly happy 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 help retain moisture while maintaining good drainage.

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

Aftercare Tips:

• Allow the foliage to die back naturally after flowering to replenish the bulbs.
• Leave established clumps undisturbed, as they resent frequent lifting and divide naturally over time.
• Apply a mulch of compost each autumn to conserve moisture and improve soil fertility.

Top Tip:
Plant in generous drifts beneath deciduous trees or beside water where the elegant white flowers can naturalise into beautiful spring colonies over the years.
