Series III. Projects, 1918-2007

This series concerns some of the projects that Jefferson worked on during his time at the United States National Arboretum and continued after his retirement. The series contains correspondence, email, photographs, articles, information kits, telegrams, press releases, memorandum, and other papers related to the background of the projects. One project covered is the dogwood exchange program, where Japanese school children and adults collected over a half million cherry seeds and bud wood in exchange for dogwood seeds collected by Americans. The documents also contain information on the cherry tress in Potomac Park (Washington, D.C.) and the Normandale Japanese Garden in Normandale Community College (Bloomington, Minnesota). The series is arranged into three subseries: Dogwood Seed Exchange, Potomac Park Cherry Trees, and Normandale Japanese Garden Cherry Trees.
