In "Central Canadian Rose-Breeding," by Isabella Preston, "Rosa rubrifolia is a very hardy species, and was therefore used as a parent, as well as for its colored foliage. In 1920 it was successfully crossed with a form of R.rugosa. The hybrid is called R. x rubrosa, and the best of the six seedlings was named Carmenetta. The foliage and flowers are intermediate between the parents, but it grows into a larger bush than either."
