Arbor Circle
Join the Arbor Circle and invest in our gardens’ future
Arbor Circle is Seattle Botanic Gardens’ giving circle—a philanthropic community that sustains Seattle Botanic Gardens. Your annual gift of $1,000+ includes membership benefits and recognition as an investor in our gardens’ future.
Arbor Circle brings together investors who value the premier public gardens of Seattle. Together, we’re building destination botanic gardens that lead in research and community engagement, where the arts, science, cultural exchange, and reflection flourish side by side.
As your annual support grows, so does our philanthropic partnership. At the $2,500, $5,000, and $10,000+ levels, your gift expands possibilities for everyone in the city to experience the restorative power of plants.
What the Arbor Circle Includes
Arbor Circle donors give generously to ensure there will always be beautiful, vast, tended, and welcoming greenspaces in Seattle. We recognize your support through seasonal gatherings, curated learning experiences, and public donor acknowledgment of your role in the gardens’ future. From guided tours to botanical-themed holiday celebrations, you’ll have opportunities to strengthen your connection to the beauty, science, and stewardship of the gardens—and to one another—year-round.
About the Trillium Donors
Providing free access to beautiful, well-cared-for gardens depends on visionary leadership and generous support. As a $10,000+ Trillium donor, you cultivate curiosity and belonging on many levels—from preschoolers discovering the first blossoms of spring at Fiddleheads Forest School to researchers advancing conservation science for our region’s most sensitive plants.
You enable our most ambitious projects to come to life, and we honor your commitment through distinctive recognition. Throughout the year, you’ll enjoy an insider view of the transformation unfolding across Seattle Botanic Gardens.
