Summary

Fritillaria imperialis, commonly known as Imperial Fritillary, is a deciduous perennial bulb native to a range of habitats including rocky slopes, scrub, and subalpine meadows, as well as the edges of fields and cultivated land in the Middle East, Afghanistan, Pakistan, and the Western Himalayas. It can reach up to 1 meter (3 feet) in height and is characterized by its lance-shaped, glossy leaves that are arranged at intervals along the stem. The plant is crowned with a prominent whorl of bell-shaped flowers that face downward, in shades of orange-red to yellow, and topped by a ’crown’ of small leaves, which gives rise to its regal name. The flowers are particularly showy and make a bold statement in the late spring garden, typically blooming in late April to May. The blooms emit a musky odor that is effective at deterring rodents and other small animals.

Imperial Fritillary is valued for its striking appearance and is often used in border plantings, cottage gardens, and as a focal point in spring displays. It requires well-drained soil, preferably sandy or loamy, and thrives in full sun to part shade. While it is relatively easy to maintain, it is susceptible to bulb rot if overwatered or planted in poorly drained soils. It is also prone to lily beetle infestations. Despite these issues, its unique flower structure and height make it a desirable addition to many gardens.CC BY-SA 4.0
