The purpose of this article is to present Jussi Parikka's theory of medionatures. In the context of this theory, the author wants to show the research on relationships between media and plants. Although Parikka focuses primarily on "media zoology" and 'a geology of media", the author thinks that "a botany of media" could also be a fruitful field of research. In order to prove this point, the theory of Parikka is analysed with a main focus on post-humanism and materialism. Then the author describes the specific examples of medianatural relations found in The Secret Life of Plants and Stefano Mancuso's lecture on plant intelligence.
