About the University of Washington Botanic Gardens

More than 320 acres of gardens and woodlands -- including one of the oldest arboretums this side of the Mississippi -- and one of the West Coast's largest horticulture centers and libraries collectively fit under the umbrella "University of Washington Botanic Gardens."

The botanic gardens include the Washington Park Arboretum, Center for Urban Horticulture, Elisabeth C. Miller Library, Otis Hyde Herbarium and Union Bay Natural Area, all of which retain their individual names. The UW owns and manages the plant collections in the Washington Park Arboretum and works cooperatively with the city and the nonprofit Arboretum Foundation there.

The mission of the University of Washington Botanic Gardens is "sustaining managed to natural ecosystems and the human spirit through plant research, display and education." Conservation and research programs currently include the Rare Plant Care and Conservation Program -- a member of the national Center for Plant Conservation -- and restoration ecology where scientists are learning how to rehabilitate degraded ecosystems.

The University of Washington Botanic Gardens is a unit of the UW School of Environmental & Forest Science.
