The Wellesley College Botanic Gardens encompass outdoor gardens, arboretums, and greenhouses across 22 acres, holding thousands of plants from more than 1,500 taxa and over 150 plant families. Their grounds reflect successive chapters of the college’s history, from the H. H. Hunnewell Arboretum, rooted in an estate established in 1852, to the Alexandra Botanic Garden, the college’s first botanical garden collection in the late 19th century. Later additions include the Edible Ecosystem Teaching Garden and the Global Flora Conservatory, a modern center for display, teaching, and research. Together these landscapes remain a living collection central to Wellesley’s scientific and educational life.
