I am a landscape designer and have been purchasing 1000's of spring flowering bulbs from A.D.R. Bulbs for 100's of clients in the last 20 years. The bulbs have always been of top quality and if there were any problems, they have been quick to rectify. My orders are often complicated with many varieties and different amounts and they have always filled and delivered everything on time with the best customer care and attention to detail. The pictures in their catalog and website are beautiful. I have visited their facility in NY and was impressed with all their handling equipment and organization. I would highly recommend A.D.R. Bulbs to anyone in the wholesale trade who wants to purchase quality bulbs and work with genuinely nice people.

Fritillaria Imperialis 'Persica'

Fritillaria

Fritillaria persica, commonly known as Persian Lily, reaches 2 to 3 feet tall, featuring dramatic spires of deep plum-purple, bell-shaped blooms. Each raceme holds up to 30 nodding flowers, creating a bold vertical accent in the spring garden. The glaucous, blue-green foliage adds further contrast, enhancing its striking presence.

Ideal for borders, rock gardens, and naturalized plantings, this variety thrives in full sun to part shade and prefers well-drained, organically rich soil. It is deer-resistant and rabbit-resistant, returning reliably year after year for a dramatic seasonal display.

Growing and Maintenance Tips for Fritillaria Imperialis 'Persica'

Planting: Plant bulbs in fall, 5 to 6 inches deep and 5 to 6 inches apart. Handle carefully—Fritillaria bulbs are large, irregular, and prone to drying out, so plant promptly after purchase. Position bulbs on their side to prevent water from collecting in the central depression, which can cause rot.
Location: Full sun to light shade is best. Fritillaria meleagris prefers dappled light, while F. imperialis (Crown Imperial) thrives in sunnier spots.
Soil: Well-drained, humus-rich soil with a slightly acidic to neutral pH (6.0–7.0). Add grit or sand to improve drainage, especially for Crown Imperials.
Watering: Water after planting and during dry spells in spring. Once foliage dies back, reduce watering—bulbs prefer dry summer dormancy.
Temperature: Hardy in USDA zones 4–8. Bulbs require 10–14 weeks of cold to bloom properly.
Fertilization: Apply compost or a balanced fertilizer in early spring as shoots emerge. Avoid overfeeding.
Pruning: Remove spent flower stalks after blooming. Allow foliage to die back naturally to feed the bulb.
Propagation: Divide clumps every few years in summer when dormant. Replant offsets promptly.
Pest & Disease: Generally pest-resistant. Crown Imperials emit a musky scent that deters rodents and deer. Ensure good drainage to prevent rot.
