History

Illustrated historical scene for Crown Imperial

Fritillaria imperialis grows wild on rocky slopes and open woodlands from eastern Turkey through Iran, Iraq, Afghanistan, and into the western Himalayas. It was grown in Persian gardens for centuries before the Flemish botanist Carolus Clusius obtained bulbs from Constantinople in 1576, introducing it to European horticulture at the Imperial Garden in Vienna. Its unique appearance — a tall stem topped with a whorl of drooping orange bells crowned by a tuft of upright leaves — made it a sensation in Renaissance and Dutch Golden Age gardens, appearing in many still-life paintings by Bosschaert and van Huysum.

The bulbs emit a strong foxlike odor said to repel voles and deer. Modern cultivars include 'Rubra Maxima' (deep orange), 'Aurora' (red), and 'Lutea' (yellow).

The species is listed as CITES Appendix II. Native to Turkey, Iran, Afghanistan, and the Himalayas, cultivated in Persian gardens for centuries and introduced to Europe in the 1500s. Arrived in American colonial gardens by the 1700s, became a Victorian statement bulb, and remains an heirloom specialty offered by bulb specialists each fall.

Symbolism & meaning

What It Symbolizes

The Crown Imperial earns its meaning of majesty in form alone — a ring of pendulous bells beneath a crown of leaves, lifted high above the spring border. Its pungent fox-like odor, while startling to gardeners, is its other gift: the bulb's strong scent repels rodents from neighboring tulips and lilies. This is the regal guardian of the bulb bed, sovereign and protector at once.

  • Majesty — crown-shaped flower cluster above tall stem
  • Pest-proof guardian — strong odor repels rodents from nearby bulbs

Where the Name Comes From

'Fritillaria' from Latin 'fritillus' meaning dice-box, for the checkered pattern on related species; 'imperialis' means imperial, for the crown-like flower arrangement.
