  • Ghost Trees: An Augmented Reality Exhibit

    Ghost Trees is an augmented reality art show which celebrates the lives of five iconic Arboretum trees. Artist Sonia Ralston has skillfully recreated these beloved trees as 3-D digital models: visitors can scan a QR code at five signs around the Arboretum and see the trees superimposed on the landscape behind them, experiencing these iconic specimens as they once stood.

    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 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.

    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.
