About Us

The University of Washington Botanic Gardens was established in 2005 to unite the gardens and programs of the Washington Park Arboretum and Center for Urban Horticulture. As part of the School of Environmental and Forest Sciences and College of the Environment, UW Botanic Gardens is an international hub for plant science and ecosystem research, teaching, and stewardship. The nationally renowned living plant collection contains over 10,000 specimens. It's located around the shoreline of Union Bay on Lake Washington. If you’re looking for a place to walk, study, express your artistic talents, purchase a nature-inspired gift, or schedule a meeting or wedding, we invite you to visit both locations. You’ll find many opportunities for individual enjoyment and learning, as well as guided tours, classes and other programs.

Our mission is sustaining managed to natural ecosystems and the human spirit through plant research, display, and education.

Washington Park Arboretum

The Arboretum is a hidden gem on the shores of Lake Washington. Jointly managed by UW and the City of Seattle, its 230 acres are a dynamic assortment of plants found nowhere else. The City owns the land and the University owns all of the trees and plant collections. In terms of care, maintenance and management, the City takes care of the park-like functions (trails, benches, garbage) and the UW Botanic Gardens takes care of the gardens, trees, and plant collections. The Graham Visitors Center contains an information desk and a gift shop managed by the Arboretum Foundation. The Japanese Garden, located at the south end of the Arboretum, has an entrance fee and is managed by the City of Seattle.

Our Programs

In addition the two sites described above, the UWBG includes a variety of programs.

Academic Programs – Through the School of Environmental and Forest Sciences and the College of the Environment, UWBG located faculty work with students on topics such as climate impact on plants, invasive plants, and ecological restoration.  

Education and Outreach – UW Botanic Gardens has one of the most extensive outreach programs on the UW campus by providing adult education classes for home gardeners and horticulture professionals, as well as on-site tours, and events.  In addition we have a very robust hands-on education program for school children ages preschool through high school. 

Elisabeth C. Miller Library – With over 14,000 books on gardening techniques, garden design and history, native floras from around the world, and 400 magazine titles, the Miller Library has the most extensive horticulture collection in the Pacific Northwest. 

Otis Douglas Hyde Herbarium houses a collection of nearly 20,000 plant specimens that is primarily of those from the Washington Park Arboretum, including horticulturally significant plants and weeds.  They collect everything in fruit and flower and then mount each specimen and store it in a controlled environment at the Center for Urban Horticulture, with the goal to preserve the specimens indefinitely. 

Rare Plant Care and Conservation Program is dedicated to conserving Washington's native rare plants through methods including ex situ conservation, rare plant monitoring, research, reintroduction, and education. 

Orin and Ally Soest Herbaceous Garden was created to help local gardeners select plants appropriate to a variety of site conditions commonly found in Pacific Northwest urban gardens. This showcase garden delights visitors throughout the year with color and texture that evolves from season to season.

Union Bay Natural Area is a 74-acre public wildlife area and natural restoration laboratory where more than 30 years of restoration have turned this former landfill into a diverse system of meadows, woods, and wetlands.  This area is one the best bird-watching areas in the city with over 200 species of birds calling it home throughout the year.
