The great secret of iris: in perfumery it is not the flower that smells but the root. The rhizomes are dug up, cleaned and dried, then aged for about three years (sometimes up to five) — only then do irones form in them, the molecules with the characteristic scent. A tonne of roots yields just 1–2 kilograms of orris butter, which makes it one of the most expensive materials in perfumery.

How it smells: powdery, cosmetic and cool, with shades of violet, butter and a faintly earthy carrot. Iris makes a fragrance elegant and expensive, adding a feel of suede and clean skin.

The most prized iris is Florentine (Iris pallida from Tuscany). Because of the price, natural material is often supplemented with synthetic irones and ionones — they give the same powderiness, while the natural butter adds depth.

What it pairs with: iris often sits next to violet and mimosa (powdery flowers), carrot seed (warm earthiness), suede, musk and sandalwood (the feel of soft skin), and with bergamot and lavender it gives a restrained “masculine” iris. It rarely shouts — more often it makes a composition more refined and quieter.

Good to know: dried orris root was long used as powder for wigs and linen, and in Tuscany iris fields are still worked by hand — about three years pass from planting to harvesting the rhizomes, and the root then “matures” in storage for as long again.
