  • Art Show | Tree Ring Histories: The Quilts of Anna Von Mertens

    Working with international dendrochronologists, Anna Von Mertens culled source images of tree ring cross-sections from studies connecting climate variability and periods of human instability. The events represented in her quilts correlate to periods of drought recorded by the tree rings. Fading thread colors mirror and highlight historical events.

  • StoryWalks

    StoryWalks are a wonderful way for families to read and talk about nature in the Arboretum landscape. Each month we set out a seasonal story about nature by using children’s picture books with beautiful illustrations and kid-friendly language. The StoryWalks migrate weekly through locations just inside several of the most traveled gates in the Arboretum.

Heptacodium miconioides

A botanist at the Arnold Arboretum officially named and described the seven son flower in 1916. But the species would not be grown in the United States until 1980. This plant was among the first.

Community

We are growers, horticulturists, researchers, gardeners, educators, and everyone in between.

  • Community Spotlight Tiffany Enzenbacher, Head of Plant Production

    What inspires me about the Arboretum is that each plant in the landscape has a story to tell: where it came from or where the species is native, the individual who harvested the seed in the field to grow it, how it was propagated—information that makes the plant unique. All of these narratives weave together to tell the 150-year account of the Arboretum.

  • Community Spotlight Chris Copeland, Greenhouse Horticultural Technologist

    I am responsible for the horticultural quality of plants that move through our plant production facility. This involves transplanting, careful watering, and managing pests/diseases of all woody and herbaceous plants in our greenhouses and nurseries. I think folks would be interested to know about the diversity and origin of plants in our landscape. It may be hard to tell without reading every tag, but many plants were wild-collected from countries and continents around the world.

  • Community Spotlight Faye Rosin, Director of Research Facilitation

    There is so much more happening at the Arboretum than people realize, from a beautiful landscape that encourages contemplation and discovery, to research in our laboratories, to education involving public school kids or undergraduates from around the world, to art exhibits and performances… and so much more.

  • Community Spotlight Raydaliz Cancel Vazquez, Seasonal Gardener

    As I care for our plants, I love seeing the other beneficial organisms that inhabit our landscape, especially those who live in our meadow areas. I also enjoy seeing so many people—and dogs!—visiting this place every day. It is amazing to know that all the hard work we do makes many people so happy.

  • Community Spotlight Ana Maria Caballero, Outdoor Educator

    I am inspired by the absolute passion that every staff member and our volunteers possess to make this place as beautiful and as accessible to the public as possible. There are multiple entry points to conservation, education, and research—our mission—but the Arnold Arboretum as a place and its people are the conduits that make our mission come alive.
