Help with identifying this shrub please
My apologies if I do anything wrong, but this is my first post on this site.
I have a shrub in my garden which was given to me as a cutting, by someone who didn't know the name of it. Many visitors to my garden like this shrub and have asked for cuttings, so it would be nice to able to identify it.
It has just finished flowering and seems to grow quite tall if not cut back.
Hopefully from the photo it will be possible to make an identification. I have just been told it could be a Philadelphus Dame Blanche, but I would be grateful if someone could confirm this.
Thank you for your help.
