I've just been looking at my 'Caporosso' and I'd like to expand on your description. While it is true that it flowers only in the summer, it is still one of the longest flowering roses I know, being continuously and generously in bloom from late May till September. My bush is about 6 feet tall and 4-5 ft wide with no disease problems or dead wood. Of course it doesn't set hips or have interesting autumn colour and only the very slightest scent - the most unrugosa of rugosas - but it is a marvellous rose, surviving well under the dripline of a mulberry tree.
