The American Rhododendron Society (ARS) is a non-profit organization whose mission is to encourage interest in, and disseminate information about, the Rhododendron genus. It has chapters throughout the United States and Canada, as well as in Denmark, the Netherlands, Scotland, Sikkim, and Sweden.
The ARS publishes the Rhododendron and Azalea News, as well as a quarterly journal, The Journal of the American Rhododendron Society, on rhododendron culture, propagation, hybridizing, gardens, plant portraits, exploration, and scientific research. (The journal was first established in April 1947 as the Quarterly Bulletin of the American Rhododendron Society.) It also funds research on Rhododendrons and Azaleas, presents Rhododendron of the Year awards, and gives gold and silver medals to society members for outstanding service.
