Fritillaria imperialis William Rex

Crown Imperial

Amazing flowers ideal for a centre piece or focal point

A group of these majestic plants used as a focal point in a border will certainly catch the eye as they burst into flower in late spring. Rings of vibrant, brick-red, bell-shaped flowers dangle enticingly below a lush tuft of green leaves from tall, statuesque stems.


Plant in a sunny sheltered area, protected from strong winds. They look fantastic in a bed, border or container.


Happy in a humus-rich, moist soil with added grit or gravel to ensure good drainage. Allow to die back naturally after flowering, to build there strength for a repeat performance next year. Use a good quality general purpose compost for container growing and raise the pot on 'pot feet' through the winter months to help with drainage.

Crown imperials grow naturally from Turkey to Pakistan on rocky slopes and scrub land.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
