Notes:
In September 1998, the Montreal Botanical Garden (Le Jardin Botanique de Montreal) carried out a survey of its roses' resistance to black spot, powdery mildew and rust. This is one of the outstanding varieties which showed a 0% to 5% infection rate. The data was taken on well-established roses.
Some differences of opinion about breeder and date, see References for more information.
The Swedish Rose Society recommends Duc de Guiche for northern Sweden.
