Geranium Rozanne magenta this summer - why?

Hi,

This summer, my many (more than 20) geranium 'Rozanne' plants all have magenta flowers instead of blue-violet.

They are planted in both mildly acidic and mildly alkaline soils, and the color change is visible all over my garden. Sun and shade, all the same.

Any thoughts?

Here in upstate NY, we are having the hottest summer since 1922.


In the previous decade, all have bloomed blue-violet.
