Fall is the best time for planting trees and shrubs in the Pacific Northwest—so you will not want to miss our annual fall sale.

The sale is hosted by the dedicated volunteers in our Pat Calvert Greenhouse  and Plant Donations Nursery, and your tax-free plant purchases will help raise revenue to support our maintenance, education, and volunteer programs at the Arboretum.

Greenhouse discount! All plants at the Pat Calvert Greenhouse will be 25% OFF during this sale!
