American University Arboretum & Gardens

American University Arboretum & Gardens Greening the American Dream by Greening the AU Campus. Dedicated in 2004, it encompasses the entire 84-acre campus.

Nestled among the embassies and residential neighborhoods of northwest Washington, D.C., the American University Arboretum and Gardens is one of the city's hidden gems. American University is a global academic community, home to nearly 11,000 undergraduate, graduate, and law students from around 145 countries and 590 full-time faculty. Diversity is also the hallmark of AU's arboretum, which contai

ns one of the most varied collections of ornamental plantings of any university in the country. More than 2500 trees—over 130 different species and varieties—provide a shady canopy, beneath which thrives a layered understory of flowering trees, shrubs, ornamental grasses, and seasonal plantings. Beds display bold arrangements and striking combinations of plants, all carefully selected by our landscape architects and tended by staff arborists and horticulturists. Throughout the arboretum, you will find an array of pleasing features and unexpected spaces—sculpture gardens, pocket parks, ponds, and streams—that invite you to pause, for contemplation or conversation.
