In November 2004, the Virginia Tech Horticulture Garden was renamed in honor of Peggy L. Hahn, a generous benefactor to the university whose donation facilitated the garden's expansion. The Peggy Lee Hahn Pavillion was added in 2006, and the Hahn Meadow Garden was constructed in 2008. She is known for love of gardening and her outstanding service as VT's first lady; her husband, Thomas Marshall Hahn Jr., served as the president of Virginia Tech from 1962 to 1974.
The garden features hundreds of species of woody and herbaceous plants from locations across the globe. The foliage is showcased in a dwarf conifer display, perennial border, shade beds, trident maple allee, wisteria arbor, and xeriscape area. Water features include the Jane Andrews Memorial Stream Garden—which includes more than 20 species of bog and aquatic plants—and a pond surrounded by Japanese maples and beds of annuals.
