Shrub ID

TimmyMagic

I'm hoping someone can identify this shrub for me. Here it is in flower (taken last summer):



It is over 6 feet tall and part of our informal hedge. It's very woody in parts and I'd like to know what it is so I can research when it should be pruned, etc. 

Thanks.

Escallonia sp or named cultivar.

Could it be Escallonia 'Apple Blossom'? Height and flowering period sound about right.
