The paper attempts to answer the question about the place of plants and urban greenery in Warsaw during the occupation and post-war period. The theoretical framework is determined by the environmental history of the war. The author describes ruralization of Warsaw during the occupation, and the fate of trees in urban forests and gardens and parks, which became depleted or destroyed as a result of the war and overexploitation. These spaces are called by Chris Pearson as “scarred landscapes”. An important point of reference is the pre-war and post-war vision of modernizing the city, in which plants occupy an important place in the spatial planning sphere. Moreover, the paper discusses the phenomenon of “urbanization of nature”, determining in this period of what belongs to the accepted sphere of “nature” in urban space.
