A beautiful and dynamic landscape results from a design responsive to the natural environment, history, and social context of the site, as well as the user’s needs.  Join the Polly Hill Arboretum staff for an illustrated presentation of Vineyard landscapes designed by summer resident and award-winning landscape architect Michael Van Valkenburgh.  From his first Island garden in 1984, to public projects like Ag Hall and the Polly Hill Arboretum parking lot, to a contemporary green roof, Van Valkenburgh will take the audience through a variety of Island landscapes.  Discover how practical issues like soil, micro-climate, and functionality are integrated with cultural history to create successful gardens and landscapes. $10 admission ($5 PHA members). Sponsored by Middletown Nursery.  For more information, call Karin Stanley at 508-693-9426, or email her at karin@pollyhillarboretum.org.
