Campanula glomerata 'Genti White'

Have two of these gorgeous plants which have been fine in a little DIY bed at the back garden gate away from the rest of the garden.  It was really where I wheelbarrowed all the small stone dug out of the whole garden and mixed them with piles of soil and some compost a couple of years ago.  So there is nothing in this little bit which is 'precious'.

However, I love these two Campanula 'Genti White' which have been hammered by rain and wind in this corner the last week followed by very hot days with intermittent light showers - which I'm thinking might be the cause of the rust.

BUT - only one plant seems to have developed the rust.  I'm contemplating trying to take as many leaves off as possible and dead-heading and seeing how it goes - but the rust is so severe someone else might advise pulling it out and incinerating it.  (There is a small acer in between both campanulas - I'm not that familiar with acers and only transplanted it there from a pot this spring.  I can't tell from looking at the acer if there is anything affecting it at all.  It's a  pale green but it's always had intermittent brown tips on some leaves after winter and it doesn't seem to have any rust).  Both plants were nicely upright until we had hellish winds a week ago, then the rain and then the heat with showers.

Anyone any advice on what would be best to try?  Many thanks.  It's a messy little thrown together bed well away from the 'main' garden so no evidence that the rust has travelled anywhere else - yet!
