Lecture: Bill Cullina, "What Do You Mean I'm Not A Perennial?!"

Most folks are familiar with the concept of the mixed border - perennials, annuals, shrubs and evergreens blended together in a seamless composition with year-round. It sounds good in theory, but transplanting this concept into a real garden is more difficult than it seems. Not all woody plants mix well with perennials and annuals for several reasons, including differing soil and fertilization needs, incompatible growth habits, aggressive root systems, or fear of crowds. This said, there are a number of native shrubs and small trees that mix wonderfully with herbaceous perennials and annuals. Many can even be cut back every year or two just like their non-woody neighbors to control their size and promote flowering and vigorous growth. In this talk, Bill Cullina will profile his favorite fifty "natural mixers," focusing native woody plants that bring, form, texture, color and wildlife to the perennial garden.

Educated at the University of Connecticut and Hobart and William Smith College in NY, Bill Cullina began his career as a retail greenhouse manager, moving on to become research aide performing experiments and collecting data on sylvicultural practices and forest ecology.  These positions led him to become the Greenhouse Manager for the Department of Ecology and evolutionary Biology at the University of Connecticut and then Nursery Manager of Niche Gardens in Chapel Hill, NC.  He is noted for his 13 years as the Nursery Director and Head Propagator at the New England Wildflower Society where he developed the largest native plant nursery in New England, producing 75,000 woody and herbaceous plants annually for garden and restoration use. From 2009-2011, Bill was Director of Horticulture at Coastal Maine Botanical Gardens, becoming the Executive Director in 2011.

Bill is a popular lecturer and teacher for the garden, conservation and professional horticultural groups in the US and Canada.  He writes regularly on native plants and orchids for Horticulture, Fine Gardening and Garden Design magazines.  He has written five acclaimed horticultural references: Wildflowers (2000), Native Trees, Shrubs and Vines: A Guide to Using, Growing and Propagating North American Woody Plants (2002), Understanding Orchids (2004), Native Ferns, Moss and Grasses: From Emerald Carpet to Amber Wave, Serene and Sensuous plants for the Garden (2008), and Understanding Perennials (2009), all published by Houghton Mifflin.  Bill specializes in the photography of North American native plants and contributed photographs to Native Plants for Your Native Garden (2010) by Maureen Heffernan.  Most recently Bill co-authored Coastal Maine Botanical Gardens: A People’s Garden in 2011.

Bill’s recent awards include: the Scott Medal for lifetime achievement in horticulture; the prized 2012 Perennial Plant Association’s highest honor, the Award of Merit; and the 2013 George Robert White Medal for “advancing horticulture in the broadest sense”.  In May of 2013, Bill received the prestigious Award of Excellence for advancing the goals of the National Garden Clubs of America.
