Arboretum scientists have pinpointed how mother plants of a water lily species take control of rearing offspring, part of a 25-year quest to understand how mothers and fathers interact in the creation of a flowering plant seed.
Supported by a Sinnott Award, Callin Switzer with colleagues Robin Hopkins and Stacy Combes examined the unique method of pollination in mountain laurel. With the anther filaments acting as catapults, the pollen reaches speeds of 8 miles per hour, making it one of the fastest moving plants in the world! Abstract»Harvard Gazette»
At the Arboretum and across the globe, volunteers are challenging the notion that science happens behind closed doors. Citizen scientists—individuals who contribute their time and efforts towards observation and data collection—are transforming the nature of scientific discovery through their collaborative efforts with professional researchers. Around the world, citizen scientists work alongside professionals in fields ranging […]
Peter Del Tredici, Senior Research Scientist Emeritus at the Arboretum, co-authored a study on the discovery of a new hemlock from Korea. The first novel conifer species to be described in a decade, the Ulleungdo hemlock interests biologists and horticulturists due to its natural resistance to the hemlock woolly adelgid.
With three to four times the botanical diversity of North America, China is a hotspot in our search for rare and unusual plants. Last September, the Arboretum joined a two-week expedition in Sichuan with the North America-China Plant Exploration Consortium (NACPEC). Harvard Magazine’s Jonathan Shaw shares the compelling story of the team’s journey, unforeseen challenges, […]
Most wine is produced from the same 12 varieties of grapes. Agricultural crops, including wine grapes, are predicted to be greatly impacted by climate change. Published in Nature Climate Change, Elizabeth Wolkovich,Ignacio Morales-Castilla and co-workers discuss how the other ~1100 varieties of grapes available, and the diversity of their attributes, may play an important role in the future.

As The Campaign for the Living Collections sources new, rare, and endangered plant material for the Arnold Arboretum Living Collections, it also generates new knowledge and best practices for conducting expeditions. To document this information and share it with the botanical garden community, the Arboretum has created a Expedition Tool Kit [pdf] which will serve […]
Drawing for Understanding in Field Science is an innovative course for high school students that combines natural science and visual art. Developed at Brookline High School with a grant from The 21st Century Fund, the course helps students study and understand the natural world through observational drawing. The students’ botanical illustration projects are currently on […]
While the pawpaw, (Asimina triloba) is one of few native North American fruit trees, not much is known about its flower and fruit development. Juan Losada (Arboretum Fellow), Iñaki Hormaza and Jorge Lora (Jewett Prize Recipient) examined its development in American Journal of Botany. Complementing this work, the genome of Asimina triloba, 12708*A, is being sequencedwith support from an Arboretum Sequencing Award. abstract»
