The University of California Botanical Garden is a 34 acre (13.7 ha) botanical garden located on the University of California, Berkeley campus, in Strawberry Canyon. The Garden is in the Berkeley Hills, inside the city boundary of Oakland, with views overlooking the San Francisco Bay. It is one of the most diverse plant collections in the United States, and famous for its large number of rare and endangered species.
The Garden was established in 1890 on the University's central campus. It was moved to its present location in the Berkeley Hills above the main campus under the directorship of Thomas Harper Goodspeed. Its present location is also less than a mile down the road from the Lawrence Hall of Science, another renown Berkeley Hills attraction. The Garden's layout in Strawberry Canyon was designed by Goodspeed and fellow Berkeley professor and landscape architect, John William Gregg.
The Garden now contains more than 20,000 accessions, representing 324 plant families, 12,000 different species and subspecies, and 2,885 genera. Outdoor collections are in general arranged geographically, and nearly all specimens have been collected from the wild.
The major family collections include: Cactus (2,669 plants), Lily (1,193 plants), Sunflower (1,151 plants), Heath (897 plants), and Orchid (950). Other well-represented families include about 500 types of ferns and fern allies, Chinese medicinal herbs, plants of economic importance, Old rose cultivars, and California native plants. A set of greenhouses contain succulents, epiphytes, ferns, carnivorous plants, and tropicals.
The Garden's collections are in geographically organized sections, and include:African Asian
