Cramp bark is a deciduous shrub native to Europe and naturalized in North America. The plant is known by many common names, the best known being Guelder Rose in honor of the Dutch city of Gueldersland where formal cultivation of the plant originated. Cramp bark is a national symbol of Ukraine, where the plant is called Kalyna and depicted in traditional folk art, most notably in embroidery. Historically, as the name suggests, the bark of this shrub is made into extracts and tinctures, while the dried berry is used to make dark dye and ink.
