Crown imperial

Fritillaria imperialis

Fritillaria imperialis 'Rubra Maxima'

This species draws much attention with its striking gaiety of color and form. Its large, bell-shaped flowers in shades of orange, yellow, and red dangle from tufts of shiny green leaf bracts. Sitting atop sturdy, 3-foot stalks, the flowers make a surprising and regal statement in the late spring garden.

CareThese bulbous perennials needs fertile, well-drained soil in full sun. Plant at four times their own depth. The hollow-centered bulbs do best planted on their sides and surrounded with sharp sand.

PropagationSow seed in a cold frame in fall, provide winter cold treatment, and then move to cool greenhouse. Divide offsets in late summer.
