About Fritillaria meleagris

Fritillaria meleagris · also called snake's head fritillary, checkered lily · flowering

Snake's head fritillary is a delicate spring bulb famous for its nodding, chequered bell flowers in chessboard purple-and-white or pure white. A British native of damp meadows, it naturalises in moist grass and is a magnet for early bees. Plant the small bulbs in autumn in moisture-retentive soil and leave undisturbed to self-seed into drifts.

Plant type: flowering

Watch for — Lily beetle: Red lily beetles and larvae graze the foliage and flowers. Check plants from spring and remove pests by hand.

The reasons fritillaria meleagris isn't blooming

Almost every non-blooming fritillaria meleagris traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding fritillaria meleagris a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get fritillaria meleagris to flower

Maximise sun. Give fritillaria meleagris the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for fritillaria meleagris and get the feeding right with the fritillaria meleagris fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Fritillaria meleagris flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full fritillaria meleagris care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Fritillaria meleagris blooming — frequently asked questions

Why won't my fritillaria meleagris flower?

Fritillaria meleagris blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make fritillaria meleagris bloom?

Give fritillaria meleagris the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
