Iris
Iris is a perfume note that comes from orris, the rhizome of the iris plant (Iris germanica and Iris pallida), dried for years. It smells soft and powdery, with violet, woody and slightly carrot-like sides. In perfume, iris can appear in the top, heart or base notes, and often gives a smooth, polished feel.

What does iris smell like?
Iris smells like fine, slightly cool powder. There are sides of violet, wood, butter and sometimes carrot or earth. Iris is neither sweet nor fresh like citrus, so it is often described as quiet and polished.
On skin, iris feels close and soft, then grows clearer as the perfume settles. The typical iris smell comes from irones, a group of compounds that smell floral, woody and violet-like.
Where does the iris scent come from?
The iris scent in perfume comes from the rhizome, called orris. Rhizomes of Iris pallida and Iris germanica are harvested, peeled and dried for years, often five years or more. During this storage, compounds in the rhizome slowly oxidise into fragrant irones.
The rhizomes are then ground and distilled into orris butter, which has a butter-like texture. One ton of root gives only about two kilograms of orris butter, which makes iris a very expensive perfume material. A well-known growing area is the hills of Tuscany, Italy, around Florence.
Iris in a perfume
Iris can appear in every layer. In the top notes it brings a powdery feel from the start, in the heart it becomes a soft centre, and in the base it helps the perfume settle smoothly. Because real orris is costly, many perfumes also use synthetic molecules to support or replace it.
Common partners for iris are violet for the floral side, vetiver and sandalwood for wood, then leather and musk for a suede-like softness. Iris is common in floral, woody and powdery perfumes. Because iris does not project far, it is best noticed up close, and how long it lasts still depends on skin, weather and concentration.
When to wear an iris perfume
Iris suits work, formal events and air-conditioned rooms, because it is neat and never too much. In hot weather it stays comfortable since it is not sweet. Iris with woods and musk also fits dinners or family gatherings.
