One lot of seeds was from a “wild” rose found on China’s western frontier near Tibet. A resulting seedling bloomed for the first time in 1907 and was named Rosa willmottiae. ..... R. willmottiae is still in commerce. The smallish single flowers range from rose-purple to lilac-pink. Growing to roughly six to eight feet in height and width with an arching habit, the petite foliage is an attractive gray-green.

R. willmottiae flourishes in the drier riparian areas of western Sichuan; however, it has also been found in Yunnan province. A tall, somewhat spindly yet elegant bush with stiletto-like prickles, its springtime dress is of flowers in lilac-pink or mauve, mostly solitary, pinned along the sleeves of branches. The stamens display a cream color. The prickles when young are reddish, when mature the color of straw. Smooth, ovoid hips late in the year decorate the plant in orangish red. The species seems to prefer stream sides and river banks. Its various traits bear a strong likeness to the American R. gymnocarpa. Wilson, who introduced it in 1904 and again in 1910, thought it “a very pleasing plant” and named it for horticulturist Ellen Willmott who helped finance one of his expeditions.

Miss Willmott herself owned Warley Place in Essex - once the home of John Evelyn; she was a skilled gardener and was a patron in paricular of E. H. Wilson. Consequently, there are a number of plants with the epithet willmottae, for instance Rosa willmottae, which Wilson had collected from western China in 1904. Her special love was roses, and she wrote the two-volume The Genus Rosa between 1910 and 1914.
