2026 Washington Botanical Symposium Resources

Shared Stewardship

Each year, the Washington Botanical Symposium brings together botanists, land stewards, researchers, growers, and plant lovers from across the region to share discoveries about Washington’s diverse flora.

Our Native Plant Nursery Team recently attended the symposium to learn from colleagues working across many disciplines, from biodiversity research and climate resilience to seed science and restoration practices.

Below you’ll find the posters our team members contributed, along with links to additional learning opportunities at Oxbow.
