As part of a grant from the Institute of Museum and Library Services, all historic accession cards, from Abeliophyllum to Zizyphus, have been reviewed and incorporated into BG-BASE, resulting in almost 70,000 new and over 100,000 edited records. In addition, 1,700 map documents (ca. 1937–1988) representing 1,982 locations have been digitized and georeferenced. Search our legacy collections.

Living accessions can be located on the grounds by referencing a grid and directional quadrants within them. For instance, a white ash (Fraxinus americana) specimen is located in grid number 20, quadrant NE. This location, 20-NE, can be matched to a 200-foot-by-300-foot area on the grounds using this grid map.
Locations for plants that fall within named garden locations are abbreviated as follows:
