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 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.

Plant Collection Notes


The City of Seattle 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 Japanese Garden is managed and maintained by the City.

The Arboretum and Botanical Garden Committee (ABGC) advises the University of Washington, City of Seattle and The Arboretum Foundation on the management and stewardship of the Washington Park Arboretum for the benefit of current and future generations.
