With the Arboretum Foundation and the University of Washington Botanic Gardens coming together as a single, united Seattle Botanic Gardens in the months ahead, we encourage donors to continue supporting the programs and places they care most about. With programs on the UW side moving over to Seattle Botanic Gardens, we ask supporters to likewise shift their giving from UW to Seattle Botanic Gardens.

Restricted gifts directly support specific programs or spaces, including the Seattle Japanese Garden, Youth Education programs, stewardship of the Center for Urban Horticulture spaces, the Miller Library, and the Rare Plant Conservation program.

You’ll find a list of restricted funds and programs that you can choose to support in the pull-down menu of our donation form.

Giving circles bring together generous supporters who want to make a lasting philanthropic impact. At the Arboretum Foundation—soon to be Seattle Botanic Gardens—these communities sustain the care, programming, and long-term vitality of our gardens, while offering meaningful recognition and connection along the way.

We have two giving circles, each with a distinct focus.

Arbor Circle

For supporters of Seattle Botanic Gardens across all three garden sites.

Arbor Circle donors invest in the full breadth of our work—from horticultural research and plant conservation to the natural beauty visitors experience at Washington Park Arboretum, Seattle Japanese Garden, and the Center for Urban Horticulture. Explore Arbor Circle.

Camellia Circle

For supporters with a special interest in the Seattle Japanese Garden.

Camellia Circle donors invest specifically in the Japanese Garden—its living heritage, its cultural traditions, and the artisans and gardeners who tend it for the public to enjoy. Explore Camellia Circle

Both circles welcome a conversation. Email giving@arboretumfoundation.org and we’re happy to talk through what matters most to you.

Including Seattle Botanic Gardens in your future plans can have a significant impact at the Arboretum, Center for Urban Horticulture and/or Seattle Japanese Garden. Just as annual memberships of all levels help provide critical sustaining funds, your planned gift (of any amount) will help ensure these vibrant spaces in the years to come. Learn more.

Corporate & Group Volunteer Days
From March through November, we host corporate and group volunteer sessions (focused on weeding, invasive species removal, and mulching). Our horticulture staff provides tools and guidance throughout. You don’t need to have any prior experience, just a willingness to get a little dirty together. Donations to offset materials and coordination costs are always welcome. Sign up for a group work party.

Matching Gifts
Many employers will match your personal donation or volunteer time, sometimes doubling or tripling its impact. Thank you for requesting a matching gift through your employer.

Sponsorship & Giving Programs
If your company has a budget set aside for community giving or sponsorship, we’d love to talk with you about what’s possible — from event sponsorship to dedicated garden support. Peruse our 2027 sponsorship opportunities.
