Fritillaria imperialis

outdoor

Crown imperial is a stately spring bulb reaching 3-4 feet tall with whorled leaves and dramatic pendant bell-shaped flowers in orange, yellow, or red crowning the stem. Bold architectural presence makes it a focal point in spring gardens and a favorite of pollinators. Distinctive musky scent deters some garden pests.
