Elle est certes avec la rose Canina, sans épine, de Brog, la plus sensible au gel de toutes les formes de roses employées aujourd'hui comme porte-greffes ....En ce dernier hiver, de toutes les formes Canina, seule Canina Pfander demeura sans dommage. Toutes les autres: Inermis, Senff, Laxa, Brog et, en d'autres endroits, Heinsohns Rekord, se sont trouvées gelées.

Die Rosen- und Baumschulen von Peter Lambert in Trier....
Auffallend war das Wachstum von Brög's Wildling im Vergleich mit Rosa canina-Sämlingen, die versuchsweise neben einander auf Beeten ausgesäet waren. Während die Canina-Sämlinge sehr ungleich standen und bedeutend schwächer waren, zeigten die Sämlinge von Brög's Wildling einen sehr gleichmässigen Stand und ein weit kräftigeres Wachstum, obwohl der Boden, auf dem sie standen, von ganz gleicher Beschaffenheit war.

Translation:
Peter Lambert's rose and tree nurseries in Trier...
The growth of Brög's Wildling was striking in comparison to Rosa canina seedlings that were experimentally sown next to each other in beds. While the Canina seedlings stood very unequally and were significantly weaker, the Brög's Wildling seedlings showed a very even stand and a much stronger growth, although the soil on which they stood was of exactly the same quality.
