The University of Delaware Botanic Gardens (UDBG) will hold a winter mini-series on seasonal color in herbaceous perennials on Wednesday evenings, Jan. 11, 18 and 25 at Townsend Hall. John Frett, director of UDBG and professor of landscape horticulture in the College of Agriculture and Natural Resources, will look at spring, summer and late summer/fall perennials. Perennials add excitement and diversity to the landscape or garden as they burst into flower each year. Some feature colorful foliage in addition to beautiful flowers, while others add architectural and multi-season interest. Mini-series classes will meet from 6:30-8:30 p.m. in 132 Townsend Hall on the University’s South Campus. In the event of snow, classes will be held Thursday evenings. Registration and prepayment are required. Those interested in attending are asked to mail BotanicGardens@udel.edu or call 302-831-2517 to reserve a spot. The cost is $25 per class for UDBG Friends and $35 per class for non-members. To enjoy exclusive UDBG Friends benefits, join the organization online or contact Melinda Zoehrer at BotanicGardens@udel.edu. The gardens are open year round to provide ideas and inspiration, or for a quite stroll. UDBG contributes to an understanding of the relationships between plants and people through education, research, Cooperative Extension and community support.
