North Idaho Expedition - collecting Salix exigua along Priest River

 Pioneering Botanical Exploration Across the Globe

Through over 140 years of plant exploration, the Arnold Arboretum has assembled world-renowned Living Collections. Responding to global habitat destruction and climate change, the Arboretum is building on its important legacy by accelerating efforts for collecting, preserving, and studying biodiversity through the Campaign for the Living Collections. This autumn, Arboretum staff and associates collected plants in the Republic of Georgia, China, and across several states in the southeastern US. To increase the value of the Living Collections to aid science, horticulture, public education, and conservation, the Campaign will acquire approximately 400 species from native populations across the temperate zone over the next decade. Please help sustain this critical resource for Boston and the world by making a gift today. more »

Gleditsia in the Arboretum
December 3, 2016 Ned Friedman, Director of the Arnold Arboretum
The Arnold Arboretum has two wonderful clusters of honey locust trees (genus Gleditsia); one on the west flank of Peters Hill, and the other appropriately embedded in the legume (pea family) collection next to Rehder Pond. Now is a great time to literally see the (pea pod-like) fruits of these trees' labors, hanging (or on the ground) from the otherwise naked branches.
