Where to plant
These fritillarias are best planted in a rich, well drained soil in full sun where they
will grow undisturbed for many years.
How to plant in the ground
1. Select your site for your fritillaria bulbs, like the back of a border and dig in a nutrient rich
compost with added grit.
2. Plant the bulbs 30cm deep and 30cm apart, any shallower will result in poor flowering.
3. Cover with soil and water in well, firming down the soil.
How to grow in containers
1. If you have heavy clay soil, imperial fritillarias are best grown in containers or raised beds.
2. Mix equal quantities of John Innes no. 3 with a multi-purpose compost with added grit.
3. Plant as you would in the ground at 30cm deep.
1. Add a layer of compost as new shoots emerge in spring.
2. Feed with a high potassium fertiliser every two weeks once the bulbs have made a few cm of
3. Once flowering season is over, keep the foliage going until it dies back naturally.
4. When the foliage has yellowed, remove from the garden.
5. If a well-established clump starts to flower poorly, then lift the bulbs in early autumn when
dormant, improve the soil or move to a new planting area.
Pests and Diseases
The most common fritillaria pests include the red lily beetle, slugs, and snails. Beetles can either be
picked off by hand or an organic insecticide can be used if the problem persists.
