Explore 150 years of plants and people

For more than 7,000 years, the land on which the Arnold Arboretum now sits has been inhabited and used by diverse societies and cultures of Indigenous People, including most recently the Massachusett Tribe.

Planting the seeds

Established in 1872 when the trustees of the will of James Arnold transferred a portion of Arnold’s estate to the President and Fellows of Harvard College, the Arboretum has become one of the world’s most comprehensive and best documented collections of temperate woody plants, and a hub of research, horticulture, and education.
