Rosa beggeriana

Rosa beggeriana is a species of rose found in Anatolia, Iran, Afghanistan, Pakistan, all of Central Asia, Xinjiang and Gansu in China, and Mongolia.[2] It is a winter‑hardy rambler, with typically flat white (rarely light pink) flowers, and small red (becoming black‑purple) hips.[3][4] Its 'Polstjärnan' (polestar) cultivar (of uncertain parentage) is the cold‑hardiest known climbing rose.[5]
