Fritillaria Imperialis (Crown imperial/ stink lily)

Introduced from Turkey.  

The common name "imperialis" refers to the large circle of golden flowers, reminiscent of an emperor's crown. It grows from a bulb to about 3 feet in height. It bears a prominent whorl of downward facing flowers at the top of the stem, topped by a 'crown' of small leaves, giving it the name. While the original wild form is usually orange-red, various colours are found in cultivation, ranging from nearly a true scarlet through oranges to yellow. Flowering takes place in late spring, accompanied by a distinct odour.
