ABCs ABCsEditors Note:
It is with great pleasure and honor that the Portland Chapter of the American
Rhododendron Society presents this collection to the world at large.
This collection of Rhododendron Data, called the ABC's by Dr. Goheen, is a compilation of 'what you have always wanted to know about rhododendrons.' The twenty-seven articles by Dr. Goheen, a member of the Portland Chapter of the American Rhododendron Society since 1963, was published by the Portland Chapter over a period of time between 1992 and 1997 in our monthly newsletter. It is an extraordinary piece of work and we wish to thank Dr. Goheen for his gracious permission to put his work into this cohesive form.
