The American Rhododendron Society is a non-profit organization whose purpose is to encourage interest in and to disseminate information about the genus Rhododendron.  Members' experience ranges from novice to expert.  Society activities include public education, flower shows, seed exchanges, scientific studies, and communication through publications and local and national meetings.  ARS chapters are located throughout the United States and Canada and in Denmark, Finland, Holland, Scotland, Sweden and Sikkim.

Welcome from Bob MacIntyre - ARS President:
On behalf of the many thousands of rhododendron enthusiasts world wide "welcome to our web site."  Here you will find valuable resources which enable you to learn more about the selection and care of rhododendrons.  We hope this will encourage you to "grow" and appreciate the genus Rhododendron (which includes azaleas), and you will include these wonderful plants in your garden/landscape.   Rhododendrons can be grown almost anywhere in the world, from the tropics to the Himalayas (home to a large population of the species which are parents to many cultivated hybrids seen in gardens around the world).

Among Society members, you will find many who share common interests whether you are a professional grower, amateur or sophisticated gardener.  I encourage you to find a chapter in your area (listings occur on the Chapters section in the web site menu) and visit them for an opportunity to join the Society.  - "Come see what we have to offer" - We would welcome you as a member!
