Back issues of the Bulletin can now be viewed online for free at the Biodiversity Heritage Library. The digitization was paid for by a grant from the Institute of Museum and Library Services. We also publish selected articles from past issues of the Bulletin.
Published since 1937, the Washington Park Arboretum Bulletin is a quarterly botanical and horticultural journal. A benefit of Arboretum Foundation membership, it includes in-depth articles on the Arboretum collections and history, as well as general information of interest to botanists, gardeners, and plant lovers in the Pacific Northwest and beyond. You can also purchase the Bulletin at the Arboretum Shop for $5 per copy.
