The Arnold Arboretum of Harvard University discovers and disseminates knowledge of the plant kingdom to foster greater understanding, appreciation, and stewardship of Earth’s botanical diversity and its essential value to humankind.

Occupying 281 acres, the Arboretum’s living collection of trees, shrubs, and woody vines is recognized as one of the most comprehensive and best documented of its kind in the world. The living collection is supported by comprehensive curatorial documentation, herbaria containing more than 1.3 million specimens, extensive library and archival holdings, and a 43,000-square-foot state-of-the-art research center. These facilities and holdings, along with 75 full-time staff, provide the basis for research and education by Harvard faculty and students, Arboretum scholars, and visiting scientists from around the world. Investigations focus on examining plant diversity from genomic, developmental, organismic, evolutionary, and ecosystem perspectives.
