Abstract: The Saratoga Horticultural Research Foundation Collection is the organizational and research records of an association of
California horticulturalists active from 1952 to 2006. The Foundation's goal was to improve and enrich western ornamental
horticulture through the promotion of shade trees, California native plants, and drought-tolerant plants. The collection spans
the years 1938-2008 (bulk 1950-1998) and includes minutes, correspondence, financial records, research notes and data, project
plans, and photographs relating to the Foundation's operation and horticultural research.
Physical location: Researchers should contact Special Collections to request collections, as many are stored offsite.

The Saratoga Horticultural Research Foundation (SHRF) was founded in 1952 by a small group committed to improving western
horticulture. Named after the location of its original headquarters on Verde Vista Lane in Saratoga, California, the SHRF
grew out of nurseryman Ray Hartman's vision of a horticultural experiment station for developing hardy, reliable trees and
shrubs for the California landscape. Hartman engaged his longtime friend Maunsell Van Rensselaer, a horticulturalist, and
a handful of others interested in examining the possibility of establishing an experiment station as a foundation. Ultimately,
the SHRF was established as a non-profit organization under the direction of a Board of Trustees, which was guided by a Board
of Councillors drawn from prominent figures in the fields of western horticulture, arboriculture, landscape design, and botany.
The Foundation's activities were guided by a director who reported to the Board of Trustees.
Maunsell Van Rensselaer was chosen as the first director of the Foundation. During his twenty-year directorship, the Foundation
began its work to change the focus of western landscaping towards landscape plants and trees better suited to California's
Mediterranean climate. The SHRF's original focus was to promote western shade trees and native California ornamental shrubs,
but during the mid-1970s, when a period of drought struck the Sacramento and San Joaquin Valleys, the Foundation expanded
its mission to include the promotion of drought-tolerant landscaping. It encouraged the use of California native plants and
trees, shade trees to maximize cooling, and alternative plantings for heavily-watered areas. At this time, the SHRF was also
investigating plants from Australia, New Zealand, and Chile as potential low-water-use and fire-retardant introductions to
The SHRF was instrumental in developing the ornamental landscaping familiar to Californians today. The Foundation conducted
research into plant quality and propagation methods, evaluated trees and woody plants for street and shade planting, established
test sites for investigations into climate and cultural techniques, and ultimately patented varieties of magnolia, Chinese
pistache, and olive trees. The SHRF also provided its findings to members of the nursery trade, landscape architects, students,
teachers, and researchers. Among the well-known plants and trees the Foundation promoted for home and commercial landscaping
are: Liquidambar "Palo Alto" and Ginkgo biloba "Autumn Gold," which provide brilliant red and yellow fall foliage; several
varieties of Ceanothus, or California lilac, known for its spikes of purple and blue flowers; and the many varieties of Manzanita
commonly used in hedges and ground covers.
In 1984, the SHRF decided to sell its property in Saratoga and move the headquarters to a location on Murphy Avenue in San
Martin, California. In 1986, the SHRF purchased another seven acres on Silva Circle in Gilroy, California; this extra land
gave the Foundation additional room for its expanding research program.
In addition to its research work and educational outreach, the SHRF also ran a small nursery. The Foundation was known for
its spring plant sales and Fall Festival, both events during which the public could tour the nursery and purchase native and
unusual plants. Most of the outreach activities were coordinated and carried out by the Associates of the Saratoga Horticultural
Foundation, which was the SHRF's docent and fund-raising group.
The Saratoga Horticultural Research Foundation was dissolved in 2006, when the board determined that it had succeeded in its
mission to promote the widespread use of native and drought-tolerant plants. The Foundation's fifty-four years of activity
were essential in guiding nurseries to continue the Foundation's work to select, evaluate, and introduce climate-appropriate
plants to the California landscaping and gardening public.
