Diaspora Botanica
Axes and relations of plants, migration and constructed belonging – a project series
This is the introduction to the project series “Diaspora Botanica” which combines the interdisciplinary practices of design, anthropology and architecture to critically investigate the construct of territory through the lens of the natural environment.
The project series is the outcome of an interdisciplinary seminar held by Lena Renz in the winter term 2025/2026 in collaboration with the Köln International School of Design, the University of Cologne (Institute of Ethnology), and the TH Köln (Architecture). The project series encompasses 11 collaborative B.A. and M.A. student projects which explore ‘Diaspora Botanica’ in their own unique ways.
About the Seminar:
Plants and seeds are organic storages of memory, tradition and belonging. Throughout history, their expansion has carried very different meanings. Colonial powers forcibly misappropriated and relocated countless green goods for profit and power. By contrast, as part of migration culture, plants have been imported and cultivated into new living places, carrying deep practical and emotional values for their communities. Organisms are vivid cultural monuments: As living connections to a homeland left behind, they carry the scent, taste and touch of another place – promising nostalgic ways of participation through their presence, care and usage. Botanical kin, therefore, forms a currency of belonging (rooting) and intergrowth (dispersal, symbiosis, prosperity). Vegetation is a free-willed force: Liberated from social constructs such as national
borders or cultural attributions, the natural impulse reclaims abandoned buildings and shapes their surroundings, turning into a symbol of resilience, adaptability and continuity. For example, the palm trees of Los Angeles shape the cities’ appearance – even though their broad settlement is an artificial orchestration to brand the southern desert metropole. Objectified into visual narratives of a tropical paradise, they cease to be plants and become part of the infrastructure, or simply a vertical line (Wüste, 2025). But how does botany itself connect to ideas of nationality, borders or belonging?
Natural organisms spread beyond maps, national borders, properties and fences, shaping alliances with insects, wind and soil. Opposing the horizontal boundaries of society, natural hierarchies distribute considerably on the y-axis. In tropical rainforests like the Amazonas, ecosystems organizes itself vertically into distinct layers stacked in height: from the shaded forest floor to the dense understory, the sunlit canopy above it and, reaching highest, the emergent crowns that break into the open sky. Each of these strata hosts its own microclimate and community of organisms, forming acclimated niches in light, moisture and spaciousness (National Geographic Society, 2025). Likewise, the anatomy of most plants rises vertically – from the dark soil and mycelium to the roots, stem, leaves, blossoms, air and sunlight, composing living columns built along the dimensions of height. How can we redefine the taxonomy of green matter, and how do we project these categories onto human lives: as useful or invasive, cultivated or wild, desired or excluded? What are the relations of plants and communities towards their definitions of kinship and belonging? The seminar combines the interdisciplinary practices of design, anthropology and architecture to investigate and critically question the constructs of territory through the lense of our natural surroundings: infrastructures of roots and movement, traditions and growth, borders and flourishing ecosystems.
About the Lecturer: Lena Renz
Lena Renz is an audiovisual designer with international background in cities like Madrid, Frankfurt, Cologne, Paris, and Milan. Currently working as a lecturer and audiovisual researcher, her focus is the conceptualization and translation of contemporary topics into multimedia experiences. Since 2018, she is producing and mixing music as Ursula Erdmann, questioning FLINTA* perspectives in the electronic music scene. Together with her international work group WAG5, she is exploring collaborative practices in electronic music production for platforms like Schauspiel Frankfurt, Callshop Radio, EOS Radio and LiveAtRobertJohnson.
With her background in a media design apprenticeship, she participated in the Bachelor and Master study program “European Design” 2018 to 2024, which allowed her to experience three interdisciplinary study environments at Köln International School of Design, ENSCI – Les Ateliers in Paris and Politechnico di Milano. Her master’s thesis on “Anthropocenic relics” was nominated for the Cologne Design Award and provokingly examines digital memory and conservation practices through a decentralized multimedia approach. Since then, she has been teaching at institutions like the University of Cologne, University of Wuppertal and ENSCI – Les Ateliers in Paris, next to her audiovisual freelance practice.
