In 1999, Dr. John Frett, professor of landscape horticulture and current director of UDBG, started a project to establish plantings around Worrilow Hall. The goal was to extend plant collections for teaching purposes. Kirk Himelick, former professor of landscape architecture, designed a series of curvilinear mounds and beds which would serve as the backbone of the project. He also designed the space with a large central lawn that would later be used for events such as Ag Day and children’s summer camps. A fortuitous municipal construction project provided the soil fill needed to shape the garden and a donation of plants from Princeton Nursery first started the collection. Today, the garden displays an extensive collection of viburnums, witch hazels, native magnolias, winter hazels, hornbeams, and oaks. Visitors will find a number of rare shrubs and trees, such as globe-flowered magnolia (Magnolia globosa), parrotiopsis (Parrotiopsis jacquemontiana), and Chinese zelkoa (Zelkova sinica) seldom seen in most gardens and landscapes.
