Some Notable Rhododendrons In the United Kingdom
Note: This is the title of an address given at the Annual Banquet by Mr. Knight who has been, for a number of years, Director of the famous Wisley Gardens of the Royal Horticultural Society and head of the Horticultural School of that Society. The address was informal and most interesting but difficult to bring to our members who were unable to attend as it consisted of slides and remarks about them. Mr. Knight was kind enough to give me a list of the slides indicating the names of the plants and the Gardens in which they were photographed. That list is reproduced herewith as it gives some indication of which gardens Mr. Knight felt contained the more notable Rhododendron specimens, and also the varieties or species he felt were outstanding and worthy of being photographed and shown. - Ed
