As this collection demonstrates, co-production as a democratic learning process, while unbalancing typical power hierarchies and engaging with voices from the margins, has clear parallels with the call for social research to embrace nonhumans. In this chapter, I will consider what this means for research with morethan-human communities, placing the tradition of participatory action research in dialogue with attempts to know plants. This conversation seeks a way of thinking through co-production which may redress plants’ marginalisation in Western thought (Hall 2011, Marder 2013). Second, it reflects on how ‘planty knowledge’ challenges participatory research in general.
