Legacy Collection Statistics
As of May 2013, the legacy (dead) collections comprised 62,936 individual plants (including nursery holdings) belonging to 42,533 accessions representing 13,541 taxa. Taken together, the collections are considered to be one of the largest (Table 1) and best documented (Table 2) woody plant collections in North America and the world. Many of these accessions or accession lineages are of historical and botanical importance, representing the original North American introductions of Eastern Asian plants collected by Arboretum staff and affiliates such as Charles Sprague Sargent, Ernest H. Wilson [pdf], John G. Jack [pdf], Joseph Rock [pdf], and William Purdom [pdf].
