October 18, 2017, 7pm —LECTURE: "Literature into Art: Books That Changed the Way We Garden”

In this lecture, Colston Burrell examines the shifting roles that gardens have played in our culture, from Victorian bedding schemes to outdoor living rooms, and highlights some seminal books that changed the way we envision, design, plant and maintain outdoor spaces.

Pre-registration recommended.
