Volunteer community, maintenance programs, and enhancement projects

The Foundation preserves and enhances the Washington Park Arboretum through a variety of dynamic programs and projects. We recruit and manage a vibrant volunteer community that supports every facet of Arboretum operations—from grounds maintenance to fundraising events. We help fund the salaries of UW Botanic Gardens arborists, gardeners, and environmental educators working in the Arboretum. We fund revitalization projects, such as the restoration of historic Rhododendron Glen, and the creation of new horticultural displays, such as the Pacific Connections Garden. We are also the support organization for the Seattle Japanese Garden in the Arboretum.
