Notes of iris root are very common in perfumery. It would seem that an inconspicuous part of the plant after drying acquires a sweet floral-powdery aroma, reminiscent of the aroma of violets. Therefore, the iris root is often called the "violet root".
In perfumery, solid iris oil is used, obtained from the roots of three years of aging by extraction or steam distillation. The oil has an expressive honey-floral aroma and is very resistant, therefore it can be diluted repeatedly without losing its smell. In minimal concentration, it has a subtle powdery shade. In addition, iris oil is used as a fixative in compositions, so sometimes it can be found not only in the heart, but also in the base of the fragrance.
