Snowdrop
Galanthus nivalis
The first thing to flower, in January, in shade, under trees, and one of the very few bulbs that is far better planted growing and green than as a dry bulb in autumn — dried snowdrop bulbs establish poorly and that is why so many autumn plantings simply never appear.

August
Nothing to do
No sowing, planting, harvesting or pruning window falls in August.
Snowdrop’s year
Resolved for United Kingdom (general). Every window is stored against a climate event rather than a date, so a late frost pocket runs later than the band shows. What else August calls for.

Timing that travels
The band above resolves this plant's windows into months for one region. These are the windows themselves, stored against a climate event rather than a date — which is the form that survives being carried to a colder garden, a frost pocket, or next year.

On your soil
Computed by comparing this plant's recorded requirements against each soil's recorded characteristics. A recorded horticultural fact overrides the comparison where GrowingHQ holds one.
| Soil | Verdict | Why |
|---|---|---|
| Heavy clay | Prefers this soil | Heavy clay suits Snowdrop as it stands: The pH suits it: it wants 6 to 7.5, and this soil is in that range. Clay is among the soils it is recorded as suiting. The soil holds moisture, which saves a great deal of watering. |
| Sandy | Grows well here | Snowdrop grows perfectly well on sandy without special measures, though it is not the soil it would choose. |
| Chalky and alkaline | Grows well here | Snowdrop grows perfectly well on chalky and alkaline without special measures, though it is not the soil it would choose. |
| Loam | Prefers this soil | Loam suits Snowdrop as it stands: The pH suits it: it wants 6 to 7.5, and this soil is in that range. Loam is among the soils it is recorded as suiting. The soil holds moisture, which saves a great deal of watering. |
| Silty | Grows well here | Snowdrop grows perfectly well on silty without special measures, though it is not the soil it would choose. |
| Peaty and acid | Grows well here | Snowdrop grows perfectly well on peaty and acid without special measures, though it is not the soil it would choose. |
| Shallow over rock | Grows well here | Snowdrop grows perfectly well on shallow over rock without special measures, though it is not the soil it would choose. |
| Made ground and urban soil | Grows well here | Snowdrop grows perfectly well on made ground and urban soil without special measures, though it is not the soil it would choose. |

Worth a pot mainly so it can be brought up to the doorstep in February, when nothing else is happening and the flowers are small enough to be missed at a distance. Use a loam-based compost and keep the pot in a shaded place through the summer rather than baking it dry; snowdrops are woodland plants and dislike a hot dormancy.
Habit and ultimate size

Growing it
- PlantingBuy and plant them in the green — in leaf, just after flowering — rather than as dry autumn bulbs. Snowdrop bulbs desiccate badly in storage and a bag of dry ones frequently produces almost nothing, which is the commonest reason people conclude snowdrops will not grow for them.
- PropagationLift and split congested clumps immediately after flowering and replant at once at the same depth. This is how a colony is spread across a garden, and it is far faster and more reliable than buying more.
- WateringSnowdrops grow through the wettest months of the British year and need no watering whatever in the ground. Their season is the mirror image of most bulbs: in leaf from midwinter, dormant through the summer, and wanting soil that holds moisture in spring but is not stagnant. The one time water matters is after planting in the green — bulbs moved in leaf in late winter have disturbed roots and a full canopy at the same time, and a dry March fortnight straight afterwards is the usual reason a newly moved clump sulks or fails.
- FeedingFeeding is rarely the answer with snowdrops and leaf mould usually is. They are woodland plants and what they respond to is organic matter on the surface — a mulch of leaf mould or garden compost after the foliage dies back, which feeds slowly and keeps the summer soil cool and steady. If a specialist clump genuinely needs a push, a high-potash liquid feed while the leaves are green works, but never a nitrogen feed: soft growth on a plant whose leaves have to survive frost is not an improvement.

Safety and edibility
Listed as harmful to cats or dogs
Snowdrop is listed as harmful if eaten. The bulbs concentrate galantamine and related Amaryllidaceae alkaloids. Eating them causes drooling, vomiting and diarrhoea, and a large quantity can produce tremors. As with daffodils the realistic exposure is a dog digging up a fresh autumn planting rather than the growing plant.source

- ToxicitychildrenpetsThe bulbs contain galantamine and related alkaloids and cause vomiting and diarrhoea if eaten. As with daffodils the realistic risk is a bulb being mistaken for something edible, or dug up and chewed by a dog.
