While we are in the process of transitioning to Seattle Botanic Gardens, checks should still be made out to “Arboretum Foundation” through the end of our fiscal year on June 30, 2026. Our non-profit EIN will remain the same as we officially roll out our new name and organization later this year.
Renew Using Your DAF
The web application below allows you to give directly to the Arboretum Foundation from a participating donor-advised fund (DAF). When your DAF arrives, we will apply it to your membership.
