The American Rhododendron Society  is a not for profit organization whose purpose is to encourage interest and to disseminate knowledge about rhododendrons and azaleas.

It also provides a medium through which all persons interested in rhododendrons and azaleas may communicate and cooperate with others through education, meetings, publications, scientific studies, research, conservation and other similar activities.

 Membership in the Society affords, among other benefits, affiliation with a more
localized chapter.  ARS chapters are located throughout the United States and
Canada and in Denmark, Holland, Scotland, Sweden and Sikkim.
