Stories of horticulture and garden-making are often bound up with stories of empires. From the global trade in plants and the economic imperative behind botanic gardens to the acquired status and symbolism of certain plants and the realities of human exploitation, this series will explore the myriad ways in which economic and political power has influenced the seemingly commonplace activities of gardeners.
This January 8-part online series from The Gardens Trust picks up themes and ideas from the Gardens and Empires conference presented in June 2025 by English Heritage and Royal Botanic Gardens, Kew in association with the British Library. Some of the speakers from the conference will be expanding on the topics they presented, and additional researchers have been invited to share their perspectives. The series will focus on European empires and will examine their global impact and influence on plants and gardening. We will explore issues from the perspective of both the coloniser and the colonized, of individuals and institutions, of the past and continuing legacies today – and will see both the triumphs and cruelties inherent in the stories around empires, plants and gardening.
This ticket link is for the series of 8 talks at £56 or you may purchase a ticket for individual talks, costing £8. (Gardens Trust members £6 each or all 8 for £42). There will be an opportunity for Q & A after each session. Ticket holders can join each session live and/or view a recording for up to 2 weeks.
The final talk of the series will be held March 10. The expansion of the British Empire into tropical regions during the 19th century introduced previously unseen plants (often labelled as ‘exotic’) into everyday life in the United Kingdom. This talk focuses on epiphytes – plants that grow on other plants – and argues that they were not passive objects but active agents in their transport, acclimatization, and transformation beyond their natural range. Their striking visual features, such as showy flowers, turned them into desirable tropical commodities, while their minimal dependence on soil increased survival during oceanic transit. Once in Britain, epiphytes such as orchids and anthuriums drove innovations in greenhouse technology, enabling the recreation of diverse tropical climates despite the UK’s relatively harsh weather. Furthermore, their natural tendency to hybridise allowed horticulturists to interbreed species from different regions, creating artificial diversity that had never existed in nature. By examining the plants’ agency of epiphytes and their interplay with technology, this talk offers a fresh perspective on ornamental plant introduction in Victorian England.
Diego Molina is a British Academy Postdoctoral Fellow at the Geohumanities Research Group at Royal Holloway, University of London, and the Royal Botanic Gardens, Kew. Initially trained as a botanist, his latest research addresses the historically built interaction between people and plants in biodiverse cities. On this topic he has published various papers in journals such as Environmental History and Economic Botany. Additionally, he has just published his third monograph, Planting a City in the Tropical Andes (Routledge, 2024). Prior to his current fellowship, he was a Rachel Carson Fellow in Munich.
This session will be chaired by Dr Caroline Cornish of the Royal Botanic Gardens, Kew.
