Two very different fritillaries
Snake's head fritillary is one of the best bulbs for naturalising in damp grass. Scatter the bulbs and plant them where they land for a natural look, and delay mowing for about six weeks after flowering so the bulbs can build up for next year.
Crown imperial wants the opposite: full sun and sharp drainage. Its bulb has a hollow top, so planting it tilted on its side stops water sitting in it and rotting the bulb. On heavy soil, add grit to the planting hole. Leave the foliage to die back naturally after flowering.
Frequently asked questions
How do you plant crown imperial bulbs?
Plant them 15–20 cm deep, tilted on their side so water does not collect in the hollow top, in a sunny spot with well-drained soil.
Where does snake's head fritillary grow best?
In moist soil in sun or part shade. It is especially good naturalised in damp grass, where it flowers in April and May.
When should fritillaria bulbs be planted?
September to October is best. Plant promptly once the bulbs arrive so they can root before winter.
