Hydrangea - again

On 16 August I blipped the rather fine cream coloured Hydrangea Paniculata that I bought from Abi & Tom's Garden plants last year. Even more pleased to find the cream colour turns into a very fine red colour.  I'm tempted to cut the blooms and bring them indoors but will that damage the plant?
Its Silly Saturday. I don't know how observant your husband is but I did laugh when  Mr P hung out the dry washing, we'd brought in a few days ago, along with the wet.  Say no more ...
