Snowdrop

Sun

Partial shade, ideally beneath deciduous trees; full sun is suitable where the soil stays moist during spring.

Water

Keep the soil evenly moist while leaves and flowers are growing. Water established colonies during prolonged spring drought; avoid waterlogged soil, especially during summer dormancy.

Soil

Humus-rich, well-drained soil that retains some moisture; tolerates acidic, neutral and alkaline conditions.

Height

0.3-0.5 ft (0.1-0.15 m)

Spread

0.2-0.3 ft (0.06-0.09 m) per bulb, widening gradually into colonies

Flowers

Late winter to early spring; nodding white flowers with green markings on the shorter inner petals.

Foliage

Two narrow, grey-green leaves usually accompany each flowering bulb. Leaves die back in late spring or early summer.

Growth

Slow to moderate; established clumps increase through bulb offsets and sometimes seedlings.

Care needed

Low

• Plant fresh bulbs promptly in early autumn, about 3 in (8 cm) deep and 3 in (8 cm) apart; avoid shrivelled bulbs.
• Water during dry spells while the leaves are green.
• Apply a thin layer of leaf mould or well-rotted compost in autumn without burying emerging shoots.
• On poor soil, apply a light dressing of balanced bulb fertiliser after flowering, following the label rate.
• Divide crowded clumps just after flowering while the leaves are still green, keeping roots moist and replanting immediately.

Pruning. No pruning is needed. Let leaves yellow and wither naturally before removing them or mowing over a naturalised planting.

Early autumn

Plant fresh dormant bulbs promptly and water them in.

Late autumn

Add a thin mulch of leaf mould and check that the planting area drains freely.

Late winter

Enjoy flowering clumps and check emerging flowers for slug damage.

Early spring

Divide congested clumps after flowering and replant immediately at their original depth.

Spring

Water in dry weather while leaves remain green; feed lightly if the soil is poor.

Early summer

Remove fully yellowed foliage; delay mowing naturalised areas until leaves have died back.

• Plant broad drifts beneath deciduous trees for flowers before the trees leaf out.
• Edge a shaded path or entrance bed where the small winter flowers can be seen closely.
• Combine with hellebores and winter aconites for a low winter-to-spring display.
• Naturalise in lightly shaded grass that can remain unmown until the foliage dies back.
• Thread through hostas and ferns, whose later foliage fills the space left by dormant bulbs.

Garden styles it suits: Woodland, Cottage garden, English country, Winter interest, White garden and Low-maintenance.

Plant it with: Hellebores, Winter aconites, Crocuses, Cyclamen, Hostas and Ferns.

Wildlife: Flowers provide pollen and nectar for bees active on mild late-winter days. Ants can carry the seeds and help disperse them.

• Narcissus bulb fly: larvae hollow out bulbs, causing weak growth or failure to emerge. Remove and dispose of affected bulbs; buy sound planting stock.
• Snowdrop grey mould: fuzzy grey growth and rotting shoots can develop in damp conditions. Remove affected bulbs and debris, improve drainage and avoid overcrowding.
• Slugs and snails: flowers and young leaves may be chewed. Hand-pick pests and use labelled iron-phosphate bait if necessary.
• Few flowers or disappearing clumps: dried-out planting stock, waterlogging or cutting leaves too early are common causes. Plant fresh bulbs, improve drainage and retain foliage until it yellows.

Toxic to people, cats, dogs and horses if eaten. All parts contain toxic alkaloids, especially the bulbs; ingestion can cause drooling, vomiting, diarrhoea and abdominal pain, with serious poisoning possible after substantial amounts. Seek medical or veterinary advice after ingestion. Bulb sap can irritate skin.

• Giant snowdrop (Galanthus elwesii)

  Usually has broader, blue-grey leaves, with one leaf wrapping around the other at the base; common snowdrop has narrower leaves lying opposite one another.

• Spring snowflake (Leucojum vernum)

  Its six flower segments are similar in length and each has a green or yellow tip; snowdrop has three long outer segments and three much shorter inner ones.

• Summer snowflake (Leucojum aestivum)

  Taller, with several white bells on each stem and six equal-length, green-tipped flower segments; it generally flowers later in spring.

Galanthus comes from Greek words meaning 'milk flower', and nivalis is Latin for 'of the snow', referring to its white flowers and early flowering season.

Propagation. Divide established clumps just after flowering while leaves are green, or lift and separate dormant bulbs before they begin rooting in autumn. Replant immediately. Fresh seed can be sown outdoors, but seedlings usually take several years to flower.
