When the EU adopted measures against invasive alien species in 2014, Viktor Orbán sent the following message to Brussels: ‘We protect the country of Hungary, the free distillation of pálinka, honey, and the robinia!’ Said robinia, also known as false acacia, is native to North America, but came to Hungary more than 300 years ago, across the Atlantic. As a non-indigenous species it thrived and became Hungary’s most popular and common tree. The Hungarian acacia is now a national symbol and essential to the production of honey and schnapps. However, as a toxic invasive alien species that has successfully supplanted many indigenous plants, it divides expert opinion. The heated debates that surround the false acacia provide the starting point for the post-truth documentary theatre created by Kristóf Kelemen and Bence György Pálinkás, exponents of Budapest’s young independent theatre scene. Magyar akác (Hungarian Acacia) is their sharp-witted and humorous commentary on Hungary’s current politics and the ideologies of populism. As gardeners they embark on their own political campaigns, establish a movement and reassess the significance of the robinia – as a symbol of an open Hungarian society.
