'George Vancouver' rose Description

My HMF:

HelpMeFind's future is in your hands - Please do not take this unique resource for granted.

Your support of HelpMeFind is urgently needed. HelpMeFind, like all websites, needs funding to survive. We have set a premium-membership yearly subscription amount as low as possible to make user-community funding viable.

We are grateful to the many members who have signed up so far, but the number of premium-membership members remains too small for us to sustain the current support and development level. If you value HelpMeFind and want to see it continue we need your support too.

Yearly membership is only $2.00 per month and adds a host of additional features, and numerous planned enhancements, to take full advantage of the power and convenience of HelpMeFind. Click here to start your premium membership..

We of course also welcome donations of any amount. Click here to make a donation. Donations of $24 or more receive a thank-you gift of a 1-year premium membership.

As far as we have come, we feel HelpMeFind is still in its infancy. With your support we have so much more to accomplish.

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')
