Please ID my shrub for me
I would love to know what this shrub is.
I can't remember the flowers - I think maybe they were a pink-white colour, or possibly just white.
It really has overgrown and needs to be cut back, so I'd love to know what it is, so I can make sure I'm cutting it at the right time of year.
I'd like to cut it back now if I can.
Thank you for any help.
