Iris Liqueur from Elixir Craft Spirits in Oregon: "Iris takes its name from its main ingredient—genuine iris root. Iris root is legendary for its delicate, violet-like scent. For centuries, Florentines cultivated iris plants in their vineyards to enhance their wines, and used iris root infusions to make floral liqueurs. The precious iris (fleur-de-lis) serves as the official emblem of Florence and the aristocracy even today."
