The app tells the story of 150 years of Arboretum plant collecting expeditions, illustrating how—and why—these plants were brought here, whether they were gathered on remote mountainsides on the other side of the world, or just a few miles away.

The app highlights a spectrum of narratives—from plant collecting, to children’s education, to research science—demonstrating that anyone can develop a deep connection with plants.

The Arnold Arboretum of Harvard University is the nation’s oldest public arboretum. A City of Boston public park, the Arboretum was designed by Frederick Law Olmsted, and is home to over 16,000 trees, shrubs, and vines. The members of the Arboretum’s horticulture, education, archives, curation, and research departments work to steward and share these collections.
