Travelling Seeds. Vegetal Memory as Testimony to Colonial History

The starting point for this investigation is the herbarium of adventive plants at the Übersee-Museum in Bremen—a collection of over 900 species of adventive plants that documents the botanical consequences of colonial trade infrastructures. Building on this, two contemporary art projects that artistically interrogate this relationship are analyzed: Seeds of Change (1999–2019) by Maria Thereza Alves germinates ballast soil from European and North American port cities, revealing what official archives conceal. Bending Towards Obscure (2025) by Bubu Mosiashvili traces the history of Giant Hogweet—from ornamental plant of colonial botanical science to criminalized neophyte—and interprets its marginalization, drawing on Mbembe, Povinelli, and Glissant, as a political act. Both projects combine archival research with botanical fieldwork. They treat plants not as metaphors, but as autonomous actors within a continuum.
