The Biocultural Diaspora of Tea in the 21st Century

About | PhD

My PhD research project was intentionally designed to be interdisciplinary and was developed in partnership with Royal Holloway, University of London and Royal Botanic Gardens, Kew to address new geographies of tea production in the 21st Century.

Tea cultivation is experiencing a renaissance in Europe and North America, with an expanding number of tea growers and makers supplying niche specialty teas to consumers globally, chiefly facilitated via Internet marketing. I find this human behavior paired with historical context fascinating. Therefore, my research examines the implications of this phenomenon for cultures of tea production, our understanding of tea’s geographies, and, importantly, tea’s biodiversity as we all face climate uncertainty and stress.

This project has grown out of my research into the historic tea specimens in the Economic Botany collection at Kew. This work, spoken to below, highlighted the significance of these specimens in documenting successive introductions of tea cultivation, first in Assam, then in Sri Lanka, Jamaica, Kenya, and other colonies in the British Empire. My doctoral research builds on this to investigate contemporary introductions of tea in the United Kingdom and the United States.

Tea in the Economic Botany Collection at Kew Gardens

About | EBC, Kew

The Royal Botanic Gardens, Kew is a large botanical institute southwest of London, England, today housing one of the most diverse living and preserved botanical and mycological collections in the world. Founded as royal gardens in the eighteenth century, Kew came under government sponsorship in 1840, with its first director, Sir William Jackson Hooker, taking up the post in 1841. The first scientific collection to be established at Kew was the Museum of Vegetable Products, opening to the public on September 20th, 1847, at a time when tea was beginning a new chapter as a global commodity. Soon renamed the Museum of Economic Botany, it displayed raw and processed plant products — both nature and culture — from around the world, both as an aid to manufacturers looking for reliable information on raw materials and as an educational attraction for the visiting public.

Over the next 60 years, a systematic effort was made to gather plant products of the world through personal, official, and industrial contacts, as well as by exchange with overseas institutions. Tea was well represented among these products, and by 1855 when the first guide to the Museum was published, already comprised an extensive collection; many of these specimens are still in the collection today. Kew’s tea collection is distinct from those of most other museums and archives in being composed primarily of tea leaves, rather than teaware or documents. Collecting activities declined in the twentieth century as other institutions took over the Museum’s role as an interface between global producers of raw materials, and manufacturers in Britain. In 1987 the contents of the former Museum buildings were moved to a purpose-built research storehouse and renamed as the Economic Botany Collection. At present it is the largest collection of its kind, containing around 100,000 specimens, 425 of which (and growing) relate to tea, with the majority coming from Asia and collected between 1847 and 1914.

About | Research

Now expanded into a doctoral project, this work is the first extended research into Kew’s tea collection in the last hundred years. It was initially prompted by two research questions: the first asks how the history of plantation crops, such as tea, is relevant to understanding their global position today. Widely traded, consumed, and culturally valued plants such as tea, cotton, and rubber, have a correspondingly wide array of complicated, often contested histories. I am curious as to how Kew and other agents of British commerce and empire were connected to today’s global cultivation of tea. To what extent did Kew’s collection represent export commodities or local products? What did the acquisition of specimens tell us about Kew’s networks, purpose, and relationship to industry? The second broad question asks whether artifacts found in material culture collections such as Kew’s can offer different complementary insights to the text and image-based resources that are more usually the basis of historical research. To do this with the help and guidance of curator and professor Dr. Mark Nesbitt, we combined our skills in collections history (MN), ethnobotany (MN/AP), and tea (AP), enabling us to elicit data from at times unassuming material - jars and boxes of old tea - taking care to draw both upon the stories of Kew, and of the communities from which these teas were sourced.

Methods include analysis of the textual evidence that accompanies objects, such as the Museum Entry Books, digitized catalog, and materials in Kew’s archive. I also conducted physical analysis, engaging in a holistic review of the objects, beginning with the labels - the basis of the textual data - and then the non-textual evidence experienced through sensory interaction with the objects through sight, touch, and smell. This method was very telling and exposed details, similarities, and themes not seen in the written record, helping to understand the collection as a whole. Prior to the pandemic arriving in England, we also arranged workshops in winter 2019, hosting visits to view the collection by about 50 members of the tea industry in the UK and Ireland—a format we hope to continue with different stakeholders. With plans to return and finish this project in spring 2020 interrupted, I continued remotely in the USA till summer 2022 when I returned with the generous sponsorship of Denys Shortt OBE. Research on this collection has continued in my doctoral project in the Geography Department at Royal Holloway, in Egham, Surry, United Kingdom beginning in 2023.

About | Browsing the EBC Catalog

The EBC is physically organized by plant family (Theaceae then Camellia then sinensis) and so is its database. The collection is best searched by broadly with the plant family, then onto genus and species. Simple searches such as a donor name or location can also be used in tandem. For tea, the collection can be searched with terms such as ‘Camellia’. The online database is updated periodically and Kew’s is in the process of adopting a new campus-wide database so stay tuned and meanwhile reach out directly with any research requests.

Further, if you are curious to read the museum’s early entry and exit books, beginning in 1847 up until 1920, they have been digitized and are available through the Biodiversity Heritage Library. Other historical material and related books can be found in Kew’s Library, Art and Archive collections located on Garden grounds and online.
