Rosa roxburghii, commonly known as Chestnut Rose, Burr Rose or the Chinquapin Rose, is native to central and east China and Japan. In its native habitat it grows in mountain forests and stream sides.

The etymological root of the binomial name Rosa is from the ancient Latin name for the rose. Roxburghii was named after John Roxburgh (1770s–1820s), an occasional overseer of Calcutta Botanic Garden.

Rosa roxburghii requires little maintenance. Pruning should be carried out once flowering is complete. Obviously if pruning is carried out after flowering no hips will follow.
