How to Grow Fritillaria
Fritillaria meleagris
Fritillaria are elegant spring-flowering bulbs ranging from the delicate chequered bells of Snake's Head Fritillary (F. meleagris) to the bold Crown Imperial (F. imperialis). Plant bulbs in autumn as soon as possible after purchase — they dry out quickly. Plant F. meleagris 10cm deep in moist, humus-rich soil in dappled shade or meadow grass. Plant F. imperialis 20cm deep on its side in fertile, well-drained soil in full sun. Leave foliage to die back naturally after flowering. Both types are fully hardy and will naturalise over time.
Yearly Lifecycle
Care Essentials
Apply a balanced granular fertiliser or bone meal when planting bulbs in autumn. A light top-dressing of bone meal in early spring as shoots emerge is beneficial.
Watch For
- Lily beetle
- Slugs and snails
- Bulb rot
Companions
Narcissus, Muscari, Primroses, Cowslips

☀️ Light
Dappled shade (meleagris) or full sun (imperialis)
F. meleagris: dappled shade or full sun in moist meadow grass. F. imperialis: full sun in a sheltered border. Both tolerate some shade but flower best with good light.
💧 Watering
Moist for meleagris; well-drained for imperialis
F. meleagris prefers consistently moist soil and thrives in damp meadows. F. imperialis needs well-drained soil and dislikes summer wet. Neither should be watered once dormant.
🌱 Fertilizing
Bone meal at planting and in early spring
Apply bone meal or balanced granular fertiliser when planting in autumn. A light top-dressing of bone meal in early spring as shoots emerge supports flowering.
✂️ Pruning
Deadhead flowers; leave foliage to die back
Remove spent flower heads to prevent seed production. Leave all foliage to die back naturally — it feeds the bulb. Do not cut, tie, or braid green leaves.
🍂 Mulching
Light leaf mould for meleagris; minimal for imperialis
A light mulch of leaf mould in autumn helps retain moisture for F. meleagris. Avoid heavy mulch over F. imperialis bulbs which prefer drier conditions.
Growing Tips
Plant bulbs promptly
Fritillaria bulbs have no protective papery skin and dry out fast. Plant within a week of purchase. If you must delay, store in slightly damp peat or vermiculite in a cool place.
Plant on the side in heavy soil
In heavy clay soil, plant Crown Imperial bulbs on their side at a slight angle. This prevents water pooling in the hollow top of the bulb and causing rot.
Naturalise in meadow grass
F. meleagris naturalises beautifully in damp meadow grass. Plant in informal drifts and avoid mowing the grass until the fritillary foliage has died back in late June.
Leave foliage to die back
Leave all foliage to die back naturally after flowering — it feeds the bulb for next year. Do not tie, braid, or cut the leaves while they are still green.
Pests & Diseases
Pest Lily Beetle
Identification: Bright scarlet beetles 8mm long on leaves. Larvae covered in black excrement on undersides of leaves. Severe defoliation possible.
- Pick off adults and larvae by hand regularly
- Check plants daily in spring when beetles are most active
- Spray with a contact insecticide containing deltamethrin or acetamiprid
Pest Slugs and Snails
Identification: Irregular holes in young emerging shoots and flower buds. Slime trails around plants.
- Apply organic slug pellets (ferric phosphate) around emerging shoots
- Encourage hedgehogs, frogs and ground beetles
- Ferric phosphate-based pellets
Disease Bulb Rot
Symptoms: Bulbs become soft, brown, and mushy. Plants fail to emerge or produce weak, yellowing growth. Foul smell from affected bulbs.
Treatment: Dig up and destroy affected bulbs. Improve drainage before replanting. Do not replant fritillaria in the same spot.
Prevention: Plant in well-drained soil. Plant Crown Imperial bulbs on their side. Avoid waterlogged conditions.
Disease Grey Mould (Botrytis) Botrytis cinerea
Symptoms: Fuzzy grey mould on leaves and flowers in damp weather. Stems may collapse.
Treatment: Remove and destroy affected parts. Improve air circulation.
Prevention: Avoid overcrowding. Do not overhead water. Remove dead foliage promptly.
Spacing & Planting
| Plant spacing | 15 cm |
| Row spacing | 25 cm |
| Mature height | 80 cm |
| Mature spread | 20 cm |
Plant bulbs in autumn, 10-15cm deep for Snake's Head Fritillary, 20cm deep for Crown Imperial. Space 10-15cm apart. Plant in groups of 10+ for best effect. Handle Crown Imperial bulbs carefully — they have a strong smell.
