It has done this for a few years now Dave and I never see any sign of mildew.
It is planted in Clay soil is well mulched and gets plenty of water.
Its always the new growth that gets affected then you dont tend to notice it during the growing season, apart from the odd few leaves that drop off.
Ive seen mildew in my garden and its certainly not mildew.
