'Longfellow'
"R. woodsii found 1 1/2 miles N.W. of Rumsey [Alberta, Canada] on NW23-33-21-W4. Its position in an east facing nook among poplars stretched its height to a measure 3.5 m. the tallest found. Under cultivation tends to spread, and does not exceed 1.5 m.
Blossoms single, smallish, pale pink, sparsely produced, fruit small."

"Back when I was in possession of a little more youth and agility, it was my habit to comb the countryside for promising wild plant material. And of course I would dig and plant a lot of stuff that eventualy proved no better than the usual. Imagine my surprise when, one day, I discovered a patch of roses in a brush patch on my own property that promised to be the ancestor of a hardy climbing rose. I kept a cane in my attic for years which measured 12 feet 3 inches."
