The culture of flax is rooted in Norman traditions. The soil is rich and the cultivable layer is deep in the region, which also benefits from a temperate oceanic climate with alternating rain and sun and mild winters and temperate summers. Flax is a plant that does not require irrigation and grows on its own in 100 days. The fields are then covered with short-lived blue flowers that only last one day. Also known as the green gold of Normandy, flax is the star of the Terre de Lin cooperative established in Saint-Pierre-le-Viger in the Seine-Maritime department.
