One gift or two?

A few months ago someone bought me this Hydrangea. It had two beautiful pure white flowers. It still has two flowers, but look at them, where has the white gone?
I like them like this too, so I feel as if I've had two presents. I wonder what colour they'll be if they flower next year.
I had to resort to a garden blip again. The last three days have been busy, with no time for pictures on Thursday and Friday, but now I'm off until Wednesday I hope I'll get out and about.
