About the Arboretum Foundation

Founded in 1935, the non-profit Arboretum Foundation raises funds and manages membership and volunteer programs to promote, protect, and enhance Washington Park Arboretum—a spectacular 230-acre greenspace just a few miles from downtown Seattle. 


By donating to the Foundation or attending Opening Night Party, you are supporting essential operations at the Arboretum, including:

• Healthy trees: our arborists identify and proactively address the effects of changing climate conditions and invasive pests.
• Biodiverse collections: our visitors learn to value the amazing variety of plants as they marvel at specimens from our region and around the globe.
• Budding naturalists: our environmental education programs inspire the next generation to learn and care about their natural surroundings.
• Vibrant volunteers: our amazing community of volunteers sustain the Arboretum by helping steward the plant collections, raise funds, and promote the park.

Since 2016, the Foundation has also been the official support organization of the world-renowned Seattle Japanese Garden, located in the Arboretum.
