my acanthus's are covered in a white "powder" (some sort of mildew?) this
also seems to affect the forget me nots nearby. I haven't managed to find
out what it is or how, if it is possible, to treat it as it makes the leaves
look ugly!

Acanthus are famous for getting mildew though I've never had quite so much
trouble forget me nots, myself. Any fungicide, such as you'd use on roses,
for example, should help you.
