Haute-Normandie (Upper Normandy) alone accounts for 50% of quality textile flax production in the world. Terre de Lin, which operates in Saint-Pierre-le-Viger in the Seine-Maritime department, benefits from a rich, fertile, and deep soil ideal for its cultivation. The cooperative is responsible for 15% of the international flax production and is a major stakeholder upstream in a textile flax industry deeply rooted in Norman traditions.
