Why have these leaves gone brown?

My dogwood leaves have started going brown, but they're not dry and crispy as I'd expect from under watering and the plant hasn't gone droopy. A similar problem is appearing on the hydrangea in the front garden.

any ideas?

    Probably frost damage.  They will recover.   If it's been dry lately, make sure you water them, especially the hydrangea.

    Frost damage ... we've had so many reports and evidence of this in the past week since the temperatures plummeted due to a very chilly wind from the north east.

    You're absolutely right Sal.

    I don't believe it. 

    Do please feel free to provide conclusive , fact based , independently verified evidence though . I'd love to read up about it.

    The leaves of hydrangeas and dogwoods have been turning those colours when exposed to cold weather, both in spring and autumn, for more than 60 years to my certain knowledge, and I was taught that by my grandmother who was born before the turn of the last century. 

    That leaf discolouration is not caused by chemicals or solar geo-engineering.

    See here http://homeguides.sfgate.com/frozen-hydrangea-76174.html and scroll down to 'Assessing the damage' for a description of the colour change in frosted hydrangea leaves.

    When I had a greenhouse and had tomato plants , the leaves used to go that colour if it was cold and I forgot to shut the greenhouse door . They did not get any rain , polluted or not , on the leaves
