Demand for essential oil is growing sharply in the late nineteenth century.  Around 1880 the new model of still is designed by Joseph Marie and from 1884 on, the steam distillation makes its appearance. Straight the early 1900s the situation is changing rapidly, the cultivation of lavender in poor areas is advocated as a remedy to the rural exodus and the abandonment of the mountains. 
Thus around 1905 the brothers Marie from Sault  had the idea to collect seedlings in natural lavanderaies to transplant them in their property located in the Val de Sault. 
The golden age of lavender: It is between 1910 and 1914 that started the "second era" of lavender. Grasse perfumers find that the lavender of the Sault and Lagarde gives an essence of quality.  Buyers are rushing, brokers are increasing and during the decade 1920 - 1930 we are witnessing a real fever for planting. This leads to a profound transformation of the environmental cultivation. 

For cutting, the local people are no longer sufficient, foreign labor is called for, especially Italians from Piedmont but also Spanish people. 
Between 1925 and 1930, taking of cuttings became obvious for the lavandin, with selections for plants with a better yield in essence and better resistance and adaptation to land. 

It is also at this period that efforts are concentrated on the mechanization and modernization of the culture.  Mr. Félix Eysseric from Nyons introduced the first prototype of a mechanical cutter in 1952. The mechanization of the cut is a real revolution and  in the 1970s the manual cut is completely abandoned. In 1995 Mr. Christian Rey from Sault invented the self-propelled cutter and the same year was built the distillery of Claux du Puits in Saint Trinit , supplied by gas boilers.

The period 1960 - 1980 marks the end of the golden years. The producers put up throughout the two decades with the endless phenomenon "yoyo" for the prices of essence.  The culture of lavender enters resolutely into the era of contemporary economic reality and it will be more and more difficult to ensure the future of this specific production. 

Even if the future is not all blue, the people here have faith in their country and  the determination specific to the people living highlands will encourage them not to give up.

Here, not satisfied to light up, the sun splashes.  The wind is his accomplice, both of them garantee this unique light that floods the fields of lavender.
