In his long-term artistic project Theatrum Botanicum, Uriel Orlow considers plants as actors on a political stage: protagonists of colonial trade, flower diplomacy, or bio-piracy. As such, they serve as a prism through which environmental colonial history can be re-negotiated. Theatrum Botanicum can be read as an attempt to decolonize both, history and nature. And for decolonizing nature, it is crucial how plants are considered as acting and living beings. If they tell stories about colonialism, how are they brought to speak?
