Washington Park Arboretum

The Washington Park Arboretum is a 230-acre public arboretum created through a long-term partnership between the City of Seattle and the University of Washington, with development beginning in the early 20th century and formalized in the 1930s. The site includes extensive collections of trees and shrubs, boardwalks on Foster Island, and seasonal displays that make it a prominent local spot for birdwatching and horticultural interest. The arboretum's history and plant collections feature in local accounts of Seattle's landscape and environmental stewardship.
