Canadian Shrub (Harp, Canada, 1969).
Here's a rose for the true collectors. Morden 6910 is still listed by it's test name because it's breeding records were largely lost. Like so many roses from the Canadian program, Morden 6910 is incredibly hardy and features striking scarlet red with intense yellow stamens. For a short time, Morden 6910 was also known as Scarlet Fire in commerce. Can be trained to climb.
