White Hydrangeas?

Still trying to identify some of the plants in our new garden.  This looks like a white Hydrangea, but can anyone confirm that please?

Bought some hanging baskets for the front of the house, as the brackets are there and they looked a bit bare.  Not the ideal time to buy them, but we got a good bargain in a garden centre where they were half price and with a bit of judicious deadheading and trimming, they look pretty good:-)

Good washing day today, with some sunshine and a gentle breeze, but of course I had none to do:-)  Typical!!
