I'm tempted to say either the Dog Rose or the Eglantine (Sweet Briar) Rose - not much to choose between them really - both smell of apples! What I can see of the rose foliage looks a bit pale - but that could be more to do with the photo than with the plant.
Another possibility would be American Pillar - though that should be a deeper pink than the photo seems to be.

alba rose? or gallica rose? a pink knock out rose? hard to say on the picture quality but i know its gotta be one of mine.

Hi, it looks to me like R Essex, a ground cover rose, grows to about 2ft high, with a spread of about 4 ft, Derek.
