Patrick Cullina, Vice President of Horticulture and Operations for Friends of the High Line, will discuss the High Line as a dynamic and emerging landscape. The High Line is a complete reuse and transformation of an abandoned industrial structure, originally constructed in 1930 to lift dangerous freight trains off the Manhattan streets, into a people friendly public park.

Lucy Hardiman
Lucy Hardiman was to the garden born—and is a fifth generation Oregon gardener. She is the principal of Perennial Partners, a garden design collective recognized for their innovative approaches to garden design. Her garden and those of her clients have appeared in many magazines and books. A popular speaker who lectures and teaches throughout the country, she writes for regional and national publications and is a contributing editor for Horticulture Magazine. Lucy will show how a well-chosen and well-planted container becomes much more than an art object when it is used purposefully. Imagine a container as the focal point of a garden bed or as a complement to a plant vignette. An exuberant container can screen an unsightly view. A series of containers can be used to indicate transitions from one part of the garden to the next or give visual cues about how to move through a space. Containers can also provide seasonal interest in borders that are past their prime. They can become the means of showcasing special collections of plants, especially beloved tender ones that need winter protection. Free.
