Yellow Lady Banks Rose (Rosa banksiae)
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.
