In less than a century, the stable concept of «French garden» is formed and consolidated, having become the result of the activity of very specific historical figures (André Lenôtre and Louis XIV) in the national consciousness of the French and in the language. The concept can be classified as a linguocultureme with a clearly expressed nationally colored semantic meaning. The article proposes to explore the ethnocultural features of the linguocultureme «French garden», as well as to determine its role and place in the national consciousness of the French, and to outline its influence on the formation of the French national picture of the world. The concept of «French garden» in the linguocultural aspect is not well-studied, which emphasizes the novelty of this work. The author conducts the research using a complex of scientific methods, including contextual-interpretive analysis, diachronic research, and analysis of linguistic and cultural objects. It is also worth noting that the author for the first time cites, in the author’s translation from French, primary sources of French scientific research and publications on the topic of landscape gardening, unknown to Russian readers. As a result of a comparison of theoretical generalization and analysis of linguistic material, the author comes to the conclusion that at certain stages of history, some concepts and traditions are formed in the collective consciousness of a nation, which can become elements of the cultural code and form the basis of the national linguistic picture of the world. Such a concept and a tradition stretching back centuries for the French is the desire to cultivate a garden, in which its aesthetic component acquires particular importance.
