  • Professor Benton Taylor Named Fellow of the Ecological Society of America

    Benton is an ecosystem ecologist working to understand how terrestrial ecosystems will respond to global change, and what the consequences will be for future carbon cycling. His work spans from tropical rainforests to the arctic tundra, focusing primarily on how plant-microbial partnerships impact ecosystem responses to rising carbon dioxide levels, warming, drought, severe weather, nutrient pollution and human land use.

  • Washington Street Gate Renewal

    Starting Monday, March 31, Washington Street Gate and Blackwell Footpath in Bussey Brook Meadow will be temporarily closed to the public during the next phase of our Entrance Improvement Project.

    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 Darcy Foster, Individual Giving Associate

    I love connecting members and donors with the landscape and the Arboretum’s mission. Together, we can ensure the Arboretum’s dynamic landscape grows in perpetuity.

    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 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.

    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.
