Living Collection

Our Living Museum

Every Plant Has a Story To Tell

The plants growing in Santa Barbara Botanic Garden make up our Living Collection. Like a piece of ancient pottery or a painting in a museum, our plants are an accessioned collection. This means we have a detailed record for each plant in the Garden. We started to keep records of our collection in 1934 and they tell a story about each plant including where it came from, how long it has been here, and more. These stories are what make a Living Collection distinct from an ordinary garden. Our Living Collection is a resource for gardeners and a tool for scientists, and the plants are ambassadors to the public, bringing awe-inspiring awareness from around California to the Garden.

How To Use Our Database

Our Living Collection features nearly a thousand different species of plants from throughout the state of California and the California Floristic Province (CFP). This area stretches from Oregon to Baja California, Mexico, and reaches inland to the Sierra Nevada. The CFP is recognized by scientists as a biodiversity hot spot, with many plant and animal species found nowhere else on Earth.

The Garden is built around an intact riparian area, Mission Creek. This living waterway supports many spectacular plants that have been growing in Mission Canyon prior to the foundation of the Garden, including coast live oaks (Quercus agrifolia), massive sycamores (Platanus racemosa), big leaf maples (Acer macrophyllum), white alders (Alnus rhombifolia), and California bay laurels (Umbellularia californica).

For information on each of the plants in our Living Collection, access our database. In it you will find a species or a plant growing in the Garden and any reference photos we have. You’ll even see where it grows so you can plan your next visit. 

Taxonomic Collections

Endless Variety 

The Garden is home to two taxonomic collections, featuring many species from a closely related group of plants. These collections are useful for comparing traits, growth habits, and the timing of flowering and fruiting.

Our Manzanita Section is an example of a taxonomic collection, meant to display the incredible diversity of manzanita (Arctostaphylos) species native to California.

Our other taxonomic collection is focused on liveforevers (Dudleya), a diverse group of succulents found throughout California. Liveforevers are ideal plants for a living collection, since their succulent leaves and thick stems are not easy to preserve in other types of botanical collections. Although our collection was impacted by the Jesusita Fire in 2009, our team is working to restore it and we continue to add new species.

The Galapagos of California

Plants of the Channel Islands

California’s Channel Islands are an archipelago of eight volcanic islands. These islands harbor unique plants and animals, many of them found nowhere else in the world.

For decades, botanists from the Garden have closely studied the plants on these unique islands. Over time we have built up the plants in our Living Collection as a resource for scientific study and a living gene bank.

We have over 200 species of plants growing in our grounds collected directly from the Channel Islands, including some of the rarest plants in California and the largest island oak (Quercus tomentella) ever recorded on the mainland. We continue to expand our Channel Islands collection so that everyone can experience the unique plant life from these special places.
