What Is Orris Root?
Orris root is the dried rhizome of the bearded iris (Iris germanica), and of related species such as Iris pallida. Irises have been grown for their roots since antiquity, especially in Tuscany around Florence, whose city symbol is the iris.
Freshly dug iris roots smell earthy and almost nothing like flowers. Only after they are peeled, dried and slowly aged for two to three years do they develop their famous fragrance: a soft, powdery, violet-like scent. This aging process is part of what makes orris one of the most precious materials in perfumery.
Orris root has two classic uses. First, it is a natural fixative: it absorbs and holds other scents, so a little orris makes potpourri, sachets and pomanders keep their fragrance much longer. Second, its delicate violet note is used in fine perfume and as a traditional botanical in gin, where it helps bind the other aromas together.
Today orris root is used by perfumers, potpourri makers, distillers and crafters, and as a scent base for homemade sachets and drawer fresheners.
Our orris root contains only dried Iris germanica root with nothing added. It is sold by weight, from small packs to bulk.
How to Use Orris Root
- Potpourri fixative: Grind and add about 1 tablespoon of orris root per 4 cups of potpourri mix, together with essential oils, and let the mix rest in a closed jar for 2 weeks.
- Sachets and pomanders: Mix ground orris root with dried lavender or rose, or roll clove-studded oranges in it to make long-lasting pomanders.
- Gin botanical: Add a very small piece to homemade gin infusions together with juniper and coriander.
Safety
For aromatic and craft use. Do not eat in large amounts. Orris powder can irritate sensitive skin and airways, so avoid inhaling the dust and test on a small area of skin first. Keep out of reach of children and pets.
