I must say, my 'Fred Loads' is well-behaved. I have two bushes alongside 'Sally Holmes', the two being products of the same breeder and, in many ways very similar in flower form except for colour and scent. (I have them in a bed which also comtains 'Dusky Maiden' another English single-semidouble rose of the same period more or less.
For those outside Britain I would point out that the rose is named after a head gardener who became nationally famous as one of the team of advisors on the radio programme 'Gardener's Question Time' and as the author of several popular books of gardening advice.

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.
