A most intriguing wild rose from North America, Rosa setigera was first observed and described by the French Botanist, André Michaux, from plants found in South Carolina in the late 18th century. Known also as the Bramble Rose, or Blackberry Rose, and named Rosa rubifolia, by the later botanist, Robert Brown, it was distributed over a very wide region of North America from the Great The cover of Mr Atomi’s book Top ‘Rosy Crystal’, bottom ‘Black Tea’ 29 Lakes region southward to Louisiana, Texas and the Carolinas, and through the northeastern states into New England.
....Many have concluded that low fertility with R. setigera led to its abandonment as a breeding candidate; Kevan, Eisikowitch, Ambrose and Kemp in an article in the Biological Journal of the Linnean Society in 1990 showed through their research that this rose species is uniquely dioecious, having male and female flowers on separate plants.
....Rosa setigera shares its wide distribution with numerous other rose species. What sets this species apart from the crowd of American wild roses are the unique qualities found in the botanical details of the rose. The flowers are born in clusters of 3 to 15 and are distinctly large, sometimes 3 to 4 inches across (7.5cm to 10cm). Foliage is similarly large in scale, and can measure 6 to 8 inches in length. The downy surfaces of the leaves, sometimes lustrous and shiny, sometimes matte and fuzzy, are indented at the veins, creating a distinctive and attractive quilted effect, not unlike that of Rosa rugosa. The clusters of bright scarlet, shiny fruits, with their prominent bristles are striking in the cold autumn months when seen against the mass of bright yellow foliage. And, Rosa setigera is a notably late blooming species, perhaps the last of the North American species to come to bloom.

Rosa setigera is the closest we get to a native climbing rose. It sends out long, weak canes set with stout, back-curved thorns and large leaves with 3 oval leaflets (5 on lower leaves) grooved deeply along the veins. There are some thorns on the petioles as well. It holds its fairly large flowers in clusters of 3 to 7 from the tips of both primary and axillary canes. Since the flowers in each cluster open up over the course of a week, starting out dark pink and fading light, a shrub in full bloom has a striking multicolor appearance.The hips are small and ruddy green. Still, R. setigera's habit and prolific flowering make it about the best wild substitute for the hybrid climbers.

"Twenty of the Best Hardy Roses for Nurserymen Selling Roses in New Hampshire" by Mike Lowe
Almost all the once-flowering old garden roses are hardy in most areas of the state. The exception is north of the notches where winter protection is a must for all but the Spinosissimas and a very few others.
Here are the ten best once-flowering roses—in no particular order.
Rosa setigera (Rosier d'Amerique). 1810. Bright pink flowers—single, in large clusters up to 25 blossoms. Blooms late—mid-July/Mid-August. Disease resistant. Grows extremely well on its own root.
