In the garden
Fritillaria imperialis Double is a bulbous perennial from the stretch of country between Turkey and the Himalaya and sits within the lily family, Liliaceae. Plants reach roughly 1.0 m and form an unmistakable spring presence, flowering between March and May. Position the bulbs in a sunny spot on loamy or clay soils that drain freely yet retain some moisture; the species prefers moist but well-drained conditions and an open, full-sun exposure. It carries a UK hardiness rating of H5 (hardy), and corresponds to USDA zones 7–9, so it tolerates typical UK winters when planted where frost and waterlogging are not combined problems. In British gardens it suits the rear of a mixed border or any site where a tall, seasonal bulb can be shown off in spring. Because the bulbs are ornamental and not edible, handle with protective gloves and keep bulbs out of reach of pets and children; follow HTA guidance if you are concerned about potentially harmful garden plants.
