Iris is a rhizome plant with more than 200 species. It is a raw material much appreciated by perfumers, but also one of the most expensive ingredient of perfumery as it is necessary to wait for 3 years for the rhizomes (underground stems) of the plant to dry before being able to distil them. After distillation, iris butter is obtained. But 1 ton of iris delivers about 2 kilos of essential oil, so its yield is very low. Its smell is quite delicate and complex although persistent: we identify powdery, woody, buttered and violet notes. You can find the scent of iris in our original musc and 555.
