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.
