To guernseygirl, who is searching for her grandfather's rose 'Charles F. Warren'. What about if you try to find the breeder’s descendants? His address is listed in his breeder’s page. Or a Mr. Len Wood at Waddesdon used to grow ‘Charles F. Warren’ in 1975.
Thank you so much for your help but I wonder if I could ask you another question? Have you any contact details for Len from Waddesdon? It has proved very difficult to find but I hope one day to finally find my grandfather's rose. Thank you.
