As early as 1931, the idea of forming a rhododendron society in the U.S. had been discussed, although the first meeting of an organized group wasn’t held until July of 1944. World War II interrupted the seed exchange from Britain on which the founders of the ARS had been dependent, so, that September, 40 interested enthusiasts, most with their own impressive collections, attended a meeting at the Public Service Building in Portland. John Henny was named the first president.

On January 9, 1945, the articles of incorporation of the American Rhododendron Society were signed. The bylaws were revised in 1951 to include local chapters in Eugene, Middle Atlantic, New York, Seattle and Tacoma. Portland was formally named a chapter in 1955. The first annual rhododendron show was held in Portland in 1948; the first international convention took place in Portland in 1961.

Today there are 87 chapters worldwide and some 2,500 members. International Conventions are held annually, alternating between East and West. The 2022 international convention, sponsored by the five chapters of ARS District 4, was the seventh hosted in Portland. Fall Regional Conferences are held in alternate East/West locations annually. Florence will be the site of the 2023 Fall conference, ahead of the Spring 2024 Convention in Bellingham, WA.
