Fougère, ], is one of the main olfactive families of perfumes. The name comes from the French language word for fern. Fougère perfumes are made with a blend of fragrances: top-notes are sweet, with the scent of lavender flowers; as the more volatile components evaporate, the scents of oakmoss, derived from a species of lichen and described as woody, sharp and slightly sweet, and coumarin, similar to the scent of new-mown hay, become noticeable. Aromatic fougère, a derivative of this class, contains additional notes of herbs, spice and/or wood.
