The world's most expensive spice is said to be saffron, a yellow substance made from the blue-flowered saffron crocus (Crocus sativa) of the eastern Mediterranean region. The major expense of saffron is in labor costs because it takes the floral parts 600-800 crocus flowers to make 0.035 oz (1 dry gram) of the spice. Saffron is mainly used to flavor foods and also as a yellow colorant of certain cooked foodstuffs, as in saffron rice.
The rhizomes of the orris (Iris florentina) are used to manufacture perfumes and cosmetics. The rhizomes must be peeled and dried before their odor, much like that of violets (Viola spp.), will develop.
