Yellow Lady Banks Rose

Vigorous spring blooming climber, nearly thornless, little fragrance. Rosa banksiae, commonly referred to as the Lady Banks' Rose, is a species of Rosa native to central and western China, in the provinces of Gansu, Guizhou, Henan, Hubei, Jiangsu, Sichuan, and Yunnan; it grows in mountains at altitudes of 500–2200 m.
It is a scrambling shrubby liana growing vigorously over other shrubs to 6 m tall. Unlike most roses, it is practically thornless, though may bear some prickles up to 5 mm long, particularly on stout, strong shoots. The leaves are evergreen, 4–6 cm long, with three to five (rarely seven) leaflets 2–5 cm long with a serrated margin. The flowers are small, 1.5-2.5 cm diameter, white or pale yellow.
