@joysabin I'm sad to say that I can't answer that right now. I started my garden over 15 years ago. At that time I sought out some interesting roses of different kinds, and certainly knew then what I was buying but, over the interim years, some have been lost to harsh winters and some I have simply forgotten the names of. When I read your question I went to check the listings on the site of the nursery from which I purchased most of my roses, all those years ago, hoping that I would find the name of the white climber pictured there, only to discover that the nursery apparently close 2 years ago. Makes me sad that such a great source of interesting and different roses is gone and we are one step closer to being restricted to the 20 or 30 varieties that the big national nurseries decide we should all grow. Can't blame the owners though, it's a difficult and uncertain business.
Just to add, it is possible that I may come across the name somewhere in my old garden records, although I have tossed some of those by now too, if so, I'll let you know.
