The Crown imperial or Kaiser's Crown (Fritillaria imperialis) is a member of the genus Fritillaria, family Liliaceae.

 It is native to a wide stretch from Anatolia across the plateau of Iran to Afghanistan, Pakistan and the Himalayan foothills. It is one of the earliest plants to be cultivated. It grows to about 1 meter (3 feet) in height, and bears lance shaped, glossy leaves, at intervals along the stem. It bears a prominent whorl of downward facing flowers at the top of the stem., topped by a 'crown' of small leaves, hence the name. While the wild form is usually orange-red, various colours are found in cultivation, ranging from nearly a true scarlet through oranges to yellow. The pendulous flowers make a bold statement in the late spring garden ; in the northern hemisphere, flowering takes place in late April or May, accompanied by a distinctly foxy odour that repels mice, moles, and other rodents.
Due to the way that the bulb is formed, with the stem emerging from a depression, it is best to plant it on its side, to prevent water causing rot at the top of the bulb. Fritillaria imperialis requires full sun for best growth, and sandy, well-drained soil for permanence. After flowering and complete drying of the leaves, the stems should be cut off just above the ground.
