Bloom Time: Spring
Fritillaria imperialis is an impressive flowering plant that grows up to 4 feet (1.2 m) tall. Each bulb produces a thick, stout, upright, ramrod-straight flowering stem, which rises to 4 feet (1.2 m) tall. The green stem leaves are lance-shaped, up to 6 inches (15 cm) long, with wavy margins, and appear in whorls around the lower 1/2 of the stem. Each stem is topped in spring with a crown of orange-red, drooping, bell-shaped flowers topped by a small pineapple-like tuft of leaf-like bracts.
USDA hardiness zone 5a to 8b: from −20 °F (−28.9 °C) to 20 °F (−6.7 °C).
How to Grow and Care
Unusual and hardy, Fritillaria bulbs produce best when planted in moist soil in a sunny to part shade location in the flower bed. Wildflower Fritillaria lilies are an excellent choice for gardeners who want out-of-the-ordinary specimens among more common spring-blooming bulbs.
Growing Fritillaria may reach 4 feet (1.2 m) or more in spring. Use wildflower Fritillarias as specimens, in groupings, or as an addition to a traditional bulb bed.
Be prepared to plant bulbs as soon as they arrive. Plant larger bulbs with the base about 5 inches (12.5 cm) below the soil surface, while smaller Fritillaria bulbs should be planted about 3 inches (7.5 cm) down. Plant bulbs in well-drained soil and keep it moist until the root system is established.
Fritillaria bulbs resist deer, squirrels, and bulb-digging rodents and may help protect other bulbs that are favorites of the critters.
