The purpose of UDBG's living plant collection is to support its educational mission with emphasis on undergraduate education,outreach programming, and the horticulture industry. A diverse collection of plants is displayed for comparative study, to inspire aesthetic design, and to illustrate ecological relationships. Its rich holdings include temperate plants from around the world, with strong emphasis on Holly, Maple, Magnolia, Oak, and Viburnum (see below for selected representatives of each). The current Plant Inventory lists the accession number (first two digits are the year the plant was acccesioned into the garden), scientific name, garden location (indicated by the bed code in the garden), common name, and plant family. The garden beds in the UDBG along with their associated codes can be found on this Location Map. Garden bed codes begn with the first letter of the garden within which they are located. The taxonomy of the Plant Inventory follows Michael A. Dirr's Manual of Woody Landscape Plants, 6th edition, to provide consistency in plant materials courses and does not necessarily reflect recent taxonomic changes.
