Arboretum Foundation

The Arboretum Foundation, a non-profit membership organization, has provided stewardship for Washington Park Arboretum since 1935. The Foundation raises funds, advocates, and manages membership and volunteer programs for the Arboretum. Fundraising events and programs include the annual Opening Night Party at the Northwest Flower & Garden Show, the Arboretum Spring Plant Sale, the Arboretum Shop, and a volunteer-managed greenhouse. Benefits of Foundation membership include a subscription to our quarterly botanical magazine, the Washington Park Arboretum Bulletin.
