Series II. Expeditions. 1978-1996. 61 folders.
The materials cover Jefferson's expeditions to Europe and Asia to study cherry and crabapple trees. The expedition to Europe covers Holland, England, and Germany, while his three expeditions to Asia were to Japan, Korea, and Taiwan. Correspondence, articles, photographs, programs, maps, charts, and other notes detailing the expeditions comprise this series and are arranged into two subseries: Europe Expedition and Asian Expeditions. See Series III. Projects and Series V. Photographs for further photographs of Jefferson's work and see Series I. Correspondence and Series III. Projects for additional correspondence. The correspondence and photographs in this series were separated from these other series to maintain original order.
- Subseries II.A. Europe Expedition. 1978-1979.
During this expedition to Europe, Jefferson studied cherries and crabapples and arranged for bud wood of some these trees, in addition to plants of Abelia, to be brought into the United States. He traveled to Holland, England, and Germany. This subseries contains correspondence, shipping material forms, and a photograph documenting his travels. The subseries is arranged chronologically.
- Subseries II.B. Asian Expeditions. 1981-1996.
The focus of the subseries is on the articles, correspondence, photographs, maps, charts, and other papers from Jefferson's expeditions to Japan, Korea, and Taiwan. These cover Jefferson's expedition to Japan from 1981-1983, where he collected bud wood from cherry trees and started the dogwood seed exchange program. His 1986 expedition took him to Japan, Korea, and Taiwan to study Prunus (cherry trees). The photographs show Jefferson in the field, various cherry trees, and the dogwood seed exchange program with Japanese children collecting cherry seeds. The information from the Americans collecting dogwood seeds is in the subseries III.A. Dogwood Seed Exchange. The maps and charts cover the locations of the collected cherry seeds and budwood from Japan that was planted on the South Farm Plant Industry Station in Beltsville, Maryland. The other papers focus on his travel proposals, proposal reviews, his final report, accession lists, distribution lists, location lists, and photographs of his expedition. Also included are color-coded envelopes which show how Jefferson organized some of his expedition papers. Each envelope has a color sticker and title that relates to various papers, with matching color stickers, throughout the collection. The subseries is arranged chronologically.

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).
