Does anyone have any more references to add to Signe Relander?
I have added many but they are not enough. I am trying to find how to tell the difference between 'Signe Relander' and 'F. J. Grootendorst' (and perhaps 'Grootendorst Supreme')

1891 Fimbriata (syn Dianthiflora) Morlet (R. rugosa Thunb. x Mme. Alfred Carriere)
1903 Mme. Norbert Levavasseur Levavasseur (Crimson Rambler x Gloire des Polyantha)
1909 Orleans Rose Levavasseur (possibly sport of Mme. Norbert Levavasseur)
1918 F. J. Grootendorst De Goey (R. rugosa Rubra x Mme. Norbert Levavasseur)
1923 Pink Grootendorst F. J. Grootendorst, 1923 (sport of F. J. Grootendorst)
1928 Signe Relander Poulsen (R. rugosa Thunb. x Orleans Rose)
1936 Grootendorst Supreme F. J. Grootendorst (sport of F. J. Grootendorst)

not anywhere near as tall as a grootendorst and perhaps darker than Grootendorst Supreme,
polyantha shaped bush, she's only waist high for a man.
