The concept of "gardening" is considered as one of a number of concepts that make up a more complex concept of "Englishness". The purpose of the article is to determine the core and periphery of the concept of "gardening", as well as a thorough analysis of its lexical representation in various lexicographic sources. In this study, the authors relied on explanatory dictionaries and a dictionary of synonyms of the English language, namely its British version. The novelty of the research lies in the fact that the representations of the linguistic and cultural components of the concept "gardening" were analyzed on the material of explanatory dictionaries and synonyms in order to clarify the lexico-semantic explication of its notional component. Having studied the obtained meanings of synonyms and the nuclear lexeme of the concept "gardening" on the basis of dictionaries, it can be concluded that the notional component of the concept can be represented in the following forms: plant study; preparation and use of soil for growing plants in the garden; landscape design of a garden or park; arrangement of gardens or parks; decorative gardening; planting plants; floriculture.
