Life
We are all familiar with the chestnut tree The flowers of this imposing hardwood specimen, clustered together in upright catkins, and its fruit (the famous chestnuts) grouped in threes in their husks, make it easily identifiable. Originally from the Mediterranean rim, it is known for its varied properties: it is drought resistant, can thrive in poor soils, likes acid ground… and is useful! For its wood and nourishing fruit obviously, but also for its leaves. Rich in tannins, they have traditionally been used as a dye by the textile industry.
Origins of the plant
Chestnut trees grow naturally and freely, without use of chemicals, on Yves Rocher’s land in La Gacilly, Brittany. At the end of June, when the leaves have finished growing but have not yet borne fruit, the agronomy team picks them by hand, making sure they only harvest healthy trees and never taking more than a third of the foliage. This keeps the trees strong and allows them to replenish themselves for the winter, so ensuring sustainable use. The leaves are then dried and crushed to extract the tannins known for their dyeing properties.
