Rosa corymbifera

Rosa corymbifera, the thicket dog rose, is a species of flowering plant in the family Rosaceae. It is native to northwestern Africa, nearly all of Europe, the Caucasus, the Middle East, and Central Asia. It primarily differs from the dog rose Rosa canina in having downier leaves, particularly on the abaxial surfaces (the undersides). The most widely used rootstock in Europe for garden roses is its cultivar 'Laxa'.
