Plants have a significant influence on human emotional and social life. We propose here an interactive experience between humans and living plants. In this paper, we focus on the manner of treating plants at the same level as a human being. Especially, we present our prototype, which allows us to visualize, at some moments a plant's biological reactions presenting its inner vitality artistically. Movements of a mechanical hand enhance the rhythm of this vitality. Through this work, we want to encourage some new axes of reflections about the human-plant relationship and their interaction for future potential concepts and technologies of communication between the two worlds.
