Identify this cemetery rose!

Somebody said it might be a Mme Plantier, but there are so many white roses in the world ... A once-bloomer. Some blossoms have the little green eye in the center. Unopened buds are only white, no pink (or just the barest hint of it). Thin green canes with little prickles. One year the blossom smelled like lemons but the next year they didn't. This rose also gets swarmed with aphids and becomes a blackspot magnet in summer lol. As you can see in the pics, sawfly larvae like it too.

This has been in the local cemetery for decades, easily, escaping years of weedeaters due to growing in a little space between a footstone and a big gravestone.
