Patricia, actually the rose I grow is labelled plain "John McNabb" and comes from Rosenposten, Denmark. I have just presumed that it is the same as this because there seems to be no sign that "true" John McNabb is available anywhere. However, confusingly, Rosenposten states that the year of introduction of their rose is 1932. My rose has pale green foliage and is repeat-flowering.
Patricia, sorry about the confusion. My rose is http://www.helpmefind.com/rose/l.php?l=2.22784&tab=1 Available from Rosenposten, Denmark. Whatever is it's correct identity, my rose is repeat blooming and has pale green foliage, in line with what is stated in the references and with the images.
Nice, delicate, light green foliage. Petals are thin but don't seen to mind rain. Medium-strong cinnamon scent similar to the rugosa parent. Few thorns.
"Mrs. John McNab R. beggeriana x rugosa hybrid, shrub to five feet, leaves large up to nine leaflets, dark green slightly rugose, prickly on under side; infra stipular spines and few thorns; flowers fully double white occasionally tinged pink in centre, fragrant, produced over a long period sepals very long. Introduced 1942."
