Crown on Crown' Crown Imperial (Fritillaria imperialis 'Prolifera')
For a perennial bulb that really wows in the landscape or garden, try this unique Crown Imperial. You can't get much more eye catching than the vibrant red blooms of Crown on Crown. Not one, but two circlets of 5 to 6 large, bell-shaped florets create these striking flower heads. Strong stems shoot straight up, rising to 36" tall, and hold the blooms proudly aloft. As a border plant, Fritillaria is a true standout. But it also makes a fascinating addition to focal point displays or as a perennialized mass planting. Butterflies and pollinators love the multiple sources of nectar this enchanting flower provides.
