Crocus sativus L (known as saffron, , fān hóng huā) is a member of the Iridaceae family. This genus of Crocus includes roughly 90 different species originating from central and southern Europe, North Africa, Middle East, and central Asia to China. Crocus sativus is widely cultivated in the Mediterranean area and Middle East because of its widespread use as a spice. From the ancient years, dried styles (the upper parts are the stigmas) of the plant were used as a food additive for its yellowish color and bitter taste.
