This article addresses the potential of participatory approaches and processes of co-creation in the context of botanical gardens. It examines how such approaches can not only help cultural heritage sector organisations to engage with different members of their public, but also how they can work with their communities to tackle globally significant societal and environmental goals. Drawing on research conducted for the EU-funded BigPicnic project, this article examines the methodological processes employed by a large consortium of botanical gardens and presents some examples of exhibitions and science cafés that attempted to both highlight issues of food security and sustainability and foster forms of knowledge that go beyond the dichotomy between experts and non-experts. A critical overview of the outcomes of this project serves to outline the potential of co-creation for promoting sustainable food futures
