A New, United Organization

One Vision, Three Locations

Bringing people & plants together for greater connection, knowledge, and inspiration

The Arboretum Foundation and University of Washington Botanic Gardens (UWBG) are engaging in serious discussions about combining strengths into a single, united organization. If we are able to conclude the negotiation of a mutually acceptable agreement, we would be able to join our people, places, expertise, and talents to:

• create a better experience for our visitors
• support more opportunities for learning and engagement
• unlock new levels of fundraising support

As a reimagined organization, we would be in a better position to deliver greater connection, knowledge, and inspiration.

Unifying the Arboretum Foundation and UWBG would bring together our three locations—the Washington Park Arboretum, the Seattle Japanese Garden, and the Center for Urban Horticulture—and allow us to reimagine the 28-acre Montlake Peninsula together.

Through re-envisioned, expanded spaces, we would be able to take everything you love about these three places—from scientific research, to recreation and community-building, to the plentiful benefits of awe-inspiring plant life—and harness them for even greater community benefit.

For additional information, we invite you to view our Shared Vision document (above; click to enlarge).

We will post regular updates on our progress to this page. Although much work remains to be done before signing is possible—and recognizing that no agreement is certain until the parties sign it—we believe that we will be able to finalize the agreement to combine our operations by Fall 2025. If you have questions or feedback, please email info@arboretumfoundation.org.
