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!
