    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.

  • 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

    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.

  • Community Spotlight Emily Hitchcock, Greenhouse Gardener

    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.

  • Community Spotlight Camilo Villouta, Putnam Fellow

    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.
