  • StoryWalks

    StoryWalks are a wonderful way for families to read and talk about nature in the Arboretum landscape. Each month we set out a seasonal story about nature by using children’s picture books with beautiful illustrations and kid-friendly language. The StoryWalks migrate weekly through locations just inside several of the most traveled gates in the Arboretum.

    My work throughout the grounds allows me to frequently interact with visitors, and I love how our shared curiosity and enthusiasm for this living landscape brings us all together.

    I am so grateful to come to work every day in a place where so many people come to find joy, relaxation, healing, and learning. Working with seeds and plants in the beginning stages of their lives is a constant reminder of the miraculous and complex life cycles that plants carry out all around us.

    There are not many other places where I could study such a diverse group of species. I love having such an exceptional collection next door to the lab, and despite spending so much time in the landscape, I still keep finding wonderful new spots with plants from around the world.

  • Community Spotlight Sarah Nechamen, Manager of Adult Programming and Events

    I love creating programs that get people excited about plants and the Arboretum and seeing the participants’ reactions first-hand. When someone feels really inspired, or excited, or awestruck because of a program I planned, there’s no better feeling.

  • Community Spotlight Daniel Faccini, PhD Candidate

    I think the Arboretum's most valuable impact is its role as a place where people can engage in a relationship with plants, something usually forgotten in big cities. The collection of hundreds of fascinating plant species offers each day a new flower, a bark you have not seen before, or a giant tree that has seen generations of visitors walking by.

  • Community Spotlight Jeffrey Scott Phillips, Assistant Manager of Horticulture
