The Royal Botanic Garden Edinburgh (RBGE) Diploma in Garden History is perfect for anyone interested in the history of British gardens. This course combines a blend of flexible online learning in your own time, with attended study days here at RBGE. You’ll explore the evolution of historic gardens, their design, conservation, and the plants and techniques that shaped them.
Since RBGE was founded in 1670 garden design styles have changed and the range of plants available significantly expanded. With one of the largest living collections of plants and such a long and rich botanical and horticultural history, RBGE is the ideal place to study garden history.
Course aims:
Explore the history and diversity of historic gardens in Britain
Evaluate the influence of related subjects of literature, art and architecture
Consider the origins and development of cultivation methods of selected plants and crops
Examine period plants, their introduction dates and use in gardens
Appraise how historic gardens and landscapes are evaluated and graded across Britain
The skills acquired during the course are invaluable to any student wishing to undertake research for heritage organisations, or as part of further academic study.
Frequently asked questions
The course is divided into the following five modules covering:
History of British Garden Design – the first module provides a solid introduction to British gardens over time including an overview of ancient garden origins.
Italian Gardens and their influence – Italian renaissance gardens had a recurring influence on British gardens and this unit considers their impact
Nineteenth century Horticulture – the incredibly diverse and rapidly changing horticultural tastes of the nineteenth century provide context for the enduring legacy of garden heritage from this period.
Historic Gardening Practices – here the extraordinary skills of gardeners are explored via a range of historic gardening practices like the cultivation of exotic flowers and fruit, or historic pruning and training techniques.
Conservation of Designed Landscapes – this unit applies knowledge from across the course to address the challenges of the evaluation and conservation of our historic garden heritage.
The two study blocks (each 3 days) complement the topics above, offering a unique opportunity to explore the rich collections held at RBGE, from the archive and rare books collection of original herbals and specialist gardening books to the living collection of over 13,000 species. Further visits to Historic Environment Scotland archive rooms and the National Map Library will equip students with the skills to research historic gardens. Guest lectures and visits to local gardens add further context.

“For anyone wanting to develop and extend their knowledge and understanding of Garden History in Britain, I would highly recommend the Diploma in Garden History at RBGE. Although mainly taught online, there was always constructive and helpful support available from the tutors as well as opportunities to discuss thoughts and ideas with other students. The study days at RBGE were always stimulating and included visits to historic gardens in Scotland to extend our learning. The content of the course was diverse and enriching and I can honestly say that my time on the course was one of the most significant and rewarding periods of education I have experienced. I learnt a colossal amount and now have a lifelong passion for Garden History and lots of new friends from the course who share my passion!”
