'Schlesingeri' red maple

Scientific Name
Acer rubrum 'Schlesingeri'

‘Schlesingeri’ showcases the earliest fall color of all red maples. It was also one of the first cultivars that the Arnold Arboretum of Harvard University introduced in the late 19th century.

Scientific Name
Cercidiphyllum japonicum

The Arnold Arboretum’s oldest katsura arrived as seed in 1878. The story of how it came here is the opening of long series of exchanges between the Arboretum and researchers in Japan.

We are arborists, recordkeepers, volunteers, researchers, educators, artists, gardeners, librarians, and everyone in between.

  • Community Spotlight A.J. Tataronis, Arborist

    The Arboretum makes connections between people and trees, which is so important in an urban environment. I have the privilege of climbing and working directly with these trees. I love being part of this community and helping to maintain this beautiful collection.

  • Community Spotlight Devika Jaikumar, Curatorial Assistant
    Devika Jaikumar

    Everyone here is so passionate about plants and how we can share that passion with the world. The impact of green spaces on mental and physical health is invaluable, and it is an honor to be part of an institution that has been committed to that mission for so long.

  • Community Spotlight Chris McArdle, Volunteer Tour Guide
    Chris McArdle leads a tour.

    Every tour brings a surprise, even after 36 years! It might be the sun catching the “Ruby Glow” witch hazel in February or the smell of toasted marshmallows from trodden katsura leaves in the fall. A squirrel running up a visitor’s trouser leg was perhaps the biggest surprise of them all.

  • Community Spotlight Ben Goulet-Scott, PhD Candidate
    Ben Goulet-Scott

    Working in the Arnold Arboretum means I am immersed in a living museum of biodiversity and inspired every day to pursue my research. Because the Arboretum offers such a popular public good to people both near and far, being based here means that I also have an incredible outlet to share my passion for biodiversity.

    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.

  • Community Spotlight Lawrence Mullings, Artist and Volunteer

    This Place nourishes the Soul as well as the Body. I returned for my health and rediscovered such beauty openly observed and freely given by all who crossed my path. This Palace of the Senses allowed me to create The Path Taken. Maybe my Exhibit can serve as a remainder of days passed, soon to return.

  • Community Spotlight Rachel Lawlor, Arboretum Gardener

    The community spirit at the Arboretum is truly palpable. From my first exposure as an Aggie intern in 2014, to being a full-time Gardener now, this has only grown. The folks who work here truly care about the Arboretum’s mission—and maybe even more so—about their colleagues.

  • Community Spotlight Larissa Glasser, Assistant Librarian

    Any walk or bike ride through the landscape is physically and spiritually restorative, all year round. I love teaching horticultural interns and students about our archives, Harvard’s shared online resources, and the importance of diversity and equal opportunities in STEM (Science, Technology, Engineering, Mathematics).
