R. rugosa var. rubra Rehder (1902) is specifically described as the purple-flowered form of the species. It was, at least at the time it was initially described, thought to be a species selection. Now Modern Roses 12 notes that R. rugosa var. rubra is "considered indistinguishable from Rosa rugosa (Thunberg)." This comment recognizes that the species produces blooms in a range of colors, including both purple and white. See Modern Roses 12.
