Polly Hill was always interested in learning more about plants and sharing that information with people. When she began growing her arboretum she made sure to join a variety of plant societies.
In a 1992 journal entry Polly writes, “They came simply, big groups, or small families. What joy it is to share the plants I love with appreciative, curious, knowledgeable, and friendly people. Viva horticulture! It restores the soul.”
The Polly Hill Arboretum is also a member of several plant societies, continuing the tradition of sharing plants with people.
