Rosa arnoldiana Sargent (R. rugosa x borboniana "Général Jacqueminot")...syn. Dawson's Hybrid Rugosa...Shrub with stout upright stems...covered with slender prickles and bristles...the young stems sparingly pubescent...Leaves 5-7 foliolate...dark green and slightly rugose above, grayish...beneath and finely pubescent on the veins....petiole...pubescent and stipitate-glandular...stipules broad...Flowers bright amaranth-purple, semi-doubt about 6 cm. across in few-flowered corymbs; bracts large...receptacle subglobose or broadly pyriform, smooth...This hybrid was raised at the Arnold Arboretum by Jackson Dawson in 1914 by fertilizing R. rugosa with "Général Jacqueminot." It is a very striking Rose...deep red color...perfectly hardy at the Arnold Arboretum....Thus the name R. arnoldiana may stand as the binomial designation for the hybrids between R. rugosa and the "Hybrid Perpetuals."

Rose breeders are singularly reticent about the plants they have used in their work, and there appear to be no printed records of the parentage of any of the Rugosa hybrids with the exception of the two which have been created in this Arboretum.
...The two Rugosa hybrids raised by Dawson at the Arboretum have proved to be good garden plants. [...] The Arnold Rose, R. Arnoldiana, was made by Dawson, by crossing R. rugosa with the hybrid Tea Rose, General Jacqueminot. It is a stout bush with good foliage and large, bright red, single flowers, and when in bloom perhaps the showiest of the Roses in the Shrub Collection.
