Despite its punchy reputation, tuberose is a surprisingly delicate flower. Compared with, say, a rose, which stays in the soil for 10 years without needing to be moved, tuberose requires year-round care as the bulbs must be dug up and separated for winter. In Grasse, where Chanel has planted the only tuberose fields in France (and the biggest in Europe), having bought a box of bulbs from a retiring farmer six years ago, they blossom only twice a year and are harvested by a team of pickers in crisp cream aprons over two weeks. The blossoms have to be hand-picked and pressed when still in bud. And they are worth their weight in gold. It takes 1,200kg of buds to produce 200g of absolute (a concentrate of the fragrance), making it one of the world’s most expensive perfume materials.
