Plant Walk: Dunn Gardens with Michelle Rau

In our walk at Dunn Gardens, we will discuss the strong history and care of Dunn Gardens, including the Olmsted Design that has been preserved, and the vision of the future while acknowledging the past. We will identify an exceptional collection of trees and shrubs, and analyze the work and preservation efforts that go into caring for State Champion trees, and others who continue to stand strong past the age of 100. We will discuss the role that nature and humans have played in this space over the years, and we will have a good time doing it!
