The Rhododendron Handbook 1998 was published in 1997. It is the last in an occasional standalone series started in 1952 and has not been revised or reprinted. Publication was prompted by the major taxonomic revision of Rhododendron in the early 1980s and the growing interest in Vireya species which had not been covered in earlier editions. It was a joint venture between the Royal Horticultural Society and the Royal Botanic Garden Edinburgh and designed to provide descriptions for species generally regarded to be in cultivation and therefore of more general use to growers and enthusiasts than the all-encompassing Revision itself.
As well as being of use as a source of reference for rhododendron species, presented in both alphabetical and strict botanical order, there is a comprehensive list of Collectors' Numbers covering rhododendron collections made in the wild from 1899 until 1996.
IMPORTANT: Taxonomic treatment of various species may have altered since the original publication.
We are grateful to the Royal Horticultural Society for granting the Group permission to offer this publication digitally.
It has been scanned and converted into searchable text using OCR technology. It is NOT perfect but it is hoped that it is sufficiently accurate to allow meaningful research.
Until now the Handbook has only been available to those who purchased the printed edition. Thanks to the generosity of the RHS, it is now made freely available to all for information and research.
