A reprise of the wildly successful 2022 event, MassQ Ball is a celebration of Boston’s cultural arts and communities of color, featuring interactive MassQ face painting and cross-cultural dancers, musicians, spoken word, sculpture, and much more. As a landscape dedicated to promoting inclusivity and free access to nature for all, the Arnold Arboretum is honored to partner with Castle of our Skins and multimedia artist Daniel Callahan to host this exciting celebration of diversity and belonging. We will open registration this summer: until then, visit MassQ’s website for a sneak peak at this year’s artists!

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.

The ‘Ernest Wilson’ silk tree exemplifies the often-unpredictable successes, and complications, of global plant collecting.
Japanese Stewartia
This Japanese stewartia—and its nearby sibling—was collected in Korea in 1917. Its taxonomic status has inspired the curiosity of generations of botanists.
