The University of California Botanical Garden at Berkeley Florilegium

Centuries before digital or analog photography was commonplace, botanists relied on detailed botanical illustrations to identify plants and flowers. While many botanical illustrations are stunning works in their own right, they are more than just pretty pictures! A botanical illustration captures, and depicts, a plant’s life cycle; its form, color and descriptive details including flower, seed, stem and leaf structure. An artist may spend countless hours painstakingly measuring all aspects of the plant in order to create an accurate documentation of its unique features. The need for this artform continues, despite the availability of high-end photographic technology.

While contemporary botanical artists may utilize photographs as a resource, it’s no substitute for working with live plant material. And many artists travel to locations around the globe, working on site to record a plant in its natural habitat, with a focus on a specific geographical region, habitat, or plant species. Artists also utilize herbaria–dried, pressed, plant material–as a resource. Working with dried plant material requires a skillful interpretation, and imagination, to bring the plant “to life” via 3-dimensional renderings.

These visual plant records provide invaluable information for botanists, gardeners and conservationists, among others. In addition, there is a tradition of recording the florilegia contained in a garden. A florilegium is a collection of illustrations featuring plants growing in a specific area such as a botanical garden. 

The UCBG Florilegium exhibitions continue this rich legacy and feature illustrations of plants in the collection by selected artists, who choose their subjects from a list of iconic plants. The works on view capture the plant information from root to leaf tip, and more. Viewers will enjoy the delicate beauty of each artwork, its subject painstakingly rendered; a testament to the artists’ technical skill and love of plants.

The project was conceived by renowned botanical illustrator and instructor, Catherine Watters, and developed with the support of staff and Advisory Board members Laura Sawczuk, Gina Baretta, and Katherine Greenberg. Advisory Board Member and former Director of Collections Chris Carmichael and Curator Holly Forbes developed the list of iconic plants from the collection for inclusion in the project.

There will be a series of five annual exhibitions, culminating in a publication of the UCBG Florilegium that will include all works in the collection!

We invite the public to explore The UCBG Florilegium—where art, history and science tangibly intersect. The exhibitions are hosted for two weeks in November and are free with Garden admission.
