The StoryWalks migrate weekly through locations just inside several of the most traveled gates in the Arboretum.

    What’s not to love? The ever-changing landscape and the opportunity to learn new things every day from passionate and caring people are the two most extraordinary aspects of the Arboretum.

    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 Grace Burgin, PhD Candidate

    For me, the Arboretum has both tangible and intangible impacts. As a scientist, I see the concrete potential our collections have for addressing important questions about biological diversity, changing climate, species interactions, and more. As someone who has spent hours simply wandering through the landscape, I know the impact this space can have on my sense of well-being, wonder, and connection with the world around me.

  • Community Spotlight Jeffrey Scott Phillips, Horticulturist

    My title is Horticulturist, but I would probably characterize my role here as being the caretaker to the roses, living mulch specialist, and native plant enthusiast. The Arnold has an incredible history of plant-loving people that I really relate to. I feel lucky to work here and look forward to it every day.
