5-6' x same. (Rosa rugosa x R. acicularis) x Grüss an Teplitz. Skinner, Manitoba, 1939.
Double lilac-lavender-rosy blooms are fragrant, lush and prolific. Very cold-hardy rounded vigorous shrub will readily sucker. Rose expert Suzanne Verrier called it “a standout among hundreds of other roses.”
The name refers to a town inside of the Riding Mountain National Park in Manitoba and is derived from an Anishinaabe phrase washagama saageygun, which translates as ‘;clear water lake.’
