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 were taken on well-established roses.
 Dr. Felicitas Svejda gives the parentage as  'Queen Elizabeth' x ('Red Dawn' x 'Suzanne') x 2 cycles of open pollination.
