Science

Our vibrant research portfolio links to botanical survey work carried out in global hotspots around the world. Working with the University of Oxford’s Department of Biology and partners further afield, this work explores fields such as evolutionary genetics, speciation and ex situ conservation.

Collections

There are currently 272 plant families and nearly 5,000 species represented in the living collections. These collections hold unique and internationally important species, which alongside their aesthetic value hold important scientific data. The plant records database is a vital tool for documenting and analysing these collections, including current taxonomy and nomenclature, provenance (wild or garden source), and conservation status.

OBGA uses the BRAHMS database software developed at the University of Oxford, which aims to explore and document biodiversity.

Heritage and Landscape

As the oldest botanic garden in the UK, we have a unique and unrivalled heritage. Our Herbarium Room, which opened to the public in 2019, physically connects the Garden with the Oxford Herbaria and showcases some of the treasures from this internationally important scientific collection. This theme will also drive the establishment of ‘historical’ borders of plants reflecting the botanical legacies of former Professors, Keepers and Curators.

Taxonomy and Evolution

Our collections are a teaching and research resource to illustrate and explain the evolution, diversity and classification of plants. In the Walled Garden, you can find our Taxonomic Beds which have been reconfigured in line with the latest DNA-based classifications. We also place a strong focus on evolution and adaptation in our glasshouse collections. Together, these collections represent a ‘living library’ for evolutionary and comparative genomics research.

Conservation and Biodiversity

As part of our commitment to delivering objectives set by the Global Strategy for Plant Conservation, we are developing and enhancing our conservation collections with a focus on local rare flora, and plants from the global biodiversity hotspots of Japan and Chile.

Plants and People

This theme celebrates the importance of plants to society and everyday life, and promotes the message that all life on earth depends on plants. Our 'Plants that Changed the World' collections in the Lower Garden and the Glasshouses highlighting plants that have changed the course of human civilisations across the globe.

Research

OBGA scientists work on a broad portfolio of collections-based and interdisciplinary research. Our work explores fundamental processes in plant evolution and reproduction using genetics and genomics, and examines potential applications of plants in technology. This research is carried out in close collaboration with other scientists at the University of Oxford’s Biology Department, Royal Botanic Gardens Kew, and other institutions around the world.

Research at the Botanic Garden focusses on the evolution of new species in ragworts (Senecio spp.) and carnivorous pitcher plants (Nepenthes spp.), as well as taxonomically complex parasitic plant groups (for example Orobanche, Cistanche and Hydnora).

Conservation

With two in five plant species threatened with extinction worldwide, conservation of the world’s flora has never been more important. At Oxford Botanic Garden and Arboretum, we are working with botanists around the world to develop ex situ conservation plant collections. Supporting biodiversity hotspots (areas rich in plant species), this research focuses on the Mediterranean Basin, the Canary Islands, Ethiopia and Japan.

The living plant collection across both sites contains about 5,000 different types of plant and holds significant conservation value. As part of our commitment to delivering against the strategy set by the Global Strategy for Plant Conservation, OBGA works with partners in Oxfordshire and across the globe to conserve rare plants. Some of those grown within our collections can be found nowhere else in the world.
