Give your yard panache with perennials lecture

Tuesday, March 22, 7-8 pm

UDBG Friends Members: $15 Nonmembers: $20

Join gardener and author Ruth Clausen to learn about the role that perennials play in the design of residential gardens. While woodies form the structure, complementary perennials can provide colorful flowers along with form, color, and texture from foliage. The maintenance and cultural needs of species and selections, including sun/shade and wet/dry soils, will be examined. Potential pest and disease problems, especially with deer, will be explained.

Ruth Clausen, trained in horticulture in the UK, has been gardening more than 50 years and was Horticulture Editor for Country Living Gardener for over seven years. She has written several garden books. In 1989, Random House published Perennials for American Gardens; Hearst Books published Dreamscaping in 2003, and 50 Beautiful Deer-Resistant Plants from Timber Press was published in 2011. In 2015, Timber Press released her latest book with Thomas Christopher, Essential Perennials.

how perennials changed our world lecture and memberhsip plant dividend distribution

Tuesday, May 17, 7 - 8:30 pm

UDBG Friends Members: Free Nonmembers: $10

Perennial horticulture made its debut in the U.S. in the Baltimore/Washington area. With the arrival of European plant and landscape visionaries like Wolfgang Oehme in the 1950's, nursery plant catalogs changed and American landscapes transformed from static evergreens and empty turf to lush expanses of grasses and perennials. But who inspired these visonaries? Please join us as we travel to Europe with Claudia West to meet the nurseryman, philosopher, and writer whom we have to thank: Karl Foerster. She'll offer a rare glimpse into his life to discover why Foerster's visioin of densely planted landscapes is still relevant today. Learn about the rich history of perennial plant experts of the time and the network of international knowledge and plant exchange that brought us the wealth of hardy plants we have today.

Claudia West is the ecological sales manager at North Creek Nurseries in Landenberg, PA. Claudia holds a MS degree of Landscape Architecture and Regional planning from the Technical University of Munich, Germany. She works closely with design and restoration professionals, offering consultation services from initial project planning stages to adaptive management strategies after project completion. Claudia's first book, Planting in a Post-Wild World, will be available for sale.
