“Digging” deeper

The University of Delaware Botanic Gardens (UDBG) began in the late 1950s with the planting of specimen trees and shrubs around “Agriculture Hall,” now Townsend Hall, the primary building for the College of Agriculture and Natural Resources. Originally established as a supportive resource for teaching horticultural science, the gardens have evolved into a valued asset for the public, green industry professionals, and campus life.
UDBG serves as a living laboratory where students in horticulture, plant science, entomology, and landscape design can gain hands-on experience in areas such as our herbaceous trials and extensive woody plant collections. Experiential learning has been a core tenet since the gardens’ establishment, providing opportunities for students to apply classroom knowledge and develop skills adjacent to their program of study.
The University of Delaware Botanic Gardens name was officially adopted in 1992 following the addition of the Herbaceous Garden. A dedicated volunteer base later formalized to found the UDBG Friends, a group that evolved into the garden’s current membership program which continues to support and advocate for the garden.
Independent installations have shaped UDBG’s collections into a dynamic outdoor laboratory. A 1996 donation from Emily Clark Diffenback established the Emily B. Clark Garden in front of Townsend Hall, which houses primarily conifers and holly trees and contains some of the gardens’ oldest specimens. Later additions include the Lepidoptera Trail, and the Wetland area (2000s). Through its history, many experts and faculty have significantly contributed to the advancement of the collections including Dr. Richard Lighty, Dr. Charles Dunham, Mr. William H. Frederick, Jr., and Dr. John Frett.
Today, UDBG spans 15 acres surrounding the College of Agriculture and Natural Resources. Support from plant sales and donors enable UDBG to employ summer interns and host students from area high schools, nurturing the next generation of horticulturists.
With over 50 years of history, UDBG continues to inspire appreciation for horticulture and serves as a vibrant resource for education and engagement across various communities.
