I am waiting to see if the named white rose ‘alba maxima’ planted this year is the same, if so I will be quite happy.
In any case, what I believe to be ‘alba maxima’ blooming. This seems to be the survivor of all survivors, lurking in the underbrush until just enough sunlight was given to it when the hedgerow across the way was cut down about 8 years ago. It had to have been planted at the driveway’s entrance, a good two generations ago, and then shaded out, forgotten entirely. It is back now, and blooms faithfully. A tall lanky bush with lovely (if brief flowers) and beautiful rose hips.
Is it quite fragrant? If so, could be Blanc Double de Coubert. I have one, if you want to compare. It’s an antique, from about 1850 – and quite impossible to kill. Blooms profusely mid-June and then a few flowers off and on during the summer.
