From Pégomas, I drove the short distance through residential neighbourhoods towards Grasse and the rose, iris and jasmine gardens that supply perfume houses like Chanel and Dior with their raw product. Much of the mimosa currently found in perfumery is synthetic, since its pom-poms are so lightweight that the quantity required to extract enough essence is considered too labour-intensive to use its true form. But there are hopeful signs this is changing: Reynaud was preparing for a visit the next day from a "grand nez" – a perfumer recognised for their ability to compose scents.
