Iris
Soft face powder, cool earth, violet petals and a faint carroty root scent.
Where it comes from

Worth knowing

About iris
Iris perfume comes from the root. Orris, as perfumers call it, is the rhizome of Iris pallida and Iris germanica, and fresh from the ground it smells of almost nothing. The plants grow for about three years. Then the rhizomes are dried and stored for another three years or more while the scent develops, so a batch takes at least six years from planting to extract.
The aged rhizomes are steam-distilled into a waxy, cream-coloured mass called orris butter. A tonne of root gives about two kilograms, roughly 0.2%. The wait and the yield are why orris is often called the most expensive material in perfumery, with the absolute quoted above €100,000 a kilo.
It smells powdery and floral, with green, woody and violet-like sides. Bois de Jasmin calls iris cold and austere, closer to something between woods and violets than to a usual flower. Florence has a long tie to it: Florentine iris powder appears in Dumas, and Tuscan growers still work through a cooperative, the Cooperativa Toscana Giaggiolo.
Most iris in mass-market perfume relies on ionones and methyl ionones, synthetics that imitate the powdery violet side for a fraction of the cost. Some carry rules of their own. IFRA restricts methyl ionone for skin sensitisation, and the EU lists alpha-isomethyl ionone as an allergen that has to be declared on the label. Those limits cover the synthetics only, and orris butter falls outside them.
For the real material, the critic at Bois de Jasmin points to Chanel No 19, Serge Lutens Iris Silver Mist and Annick Goutal Heure Exquise.
