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. Neville Arnold reports: The 'George Vancouver' rose which I grow in the open field with an excellent air flow and with Benomyl and Funginex sprays deserves about a 30% black spot rating.

Dr. Felicitas Svejda states that this rose was developed jointly with Ian Ogilvie (not W D Ogilvie) and the parentage is L83 x breeding line E10. E10 is derived from L15 x Champlain. L15 is derived from (R. kordesii x seeding ('Red Dawn' x 'Suzanne')
