Thanks Charlie - you'd think I'd know the name of my only plant! I'll give
your kind suggestion a try.

I suspect your plant is called Ville de Lyon and the mildew can either be
ignored, or cured either by heavy watering in May June and July or sprayed
with a fungicide suitable for curing mildew on roses ie sythane
