There aren’t many roots in perfumery and most of them are technically rhizomes (underground stems), but there is a royal perfume material among them: orris. It comes from the roots (rhizomes) of iris. The note of iris in perfumes is a woody/leather note coming from the twisted bulb that forms under the ground. The iris flowers have no distinct aroma and cannot yield any material useful to perfumers. The rhizomes however, when dried, pulverized and extracted produce a material (orris butter) that has a complex (musky, ambery, green, fruity and leathery) pleasant and extremely long lasting aroma.
