Haute-Normandie (Upper-Normandy) alone accounts for 50% of quality textile flax production in the world. The Terre de Lin cooperative, which operates in the region, is responsible for 15% of the international flax production. The plant benefits from a naturally rich and deep soil and an ideal temperate oceanic climate with alternating rain and sun. Flax is a particularly technical culture that requires know-how, specific equipment, responsiveness, and timing.
