Common Name: Dog rose
Rosa canina dates back to Roman times. Its hips have a high level of vitamin C, and it was often planted in WWI victory gardens. It also has many other medicinal uses. The epithet 'canina' may refer either to the sharp prickles or that the root was used to combat wounds from dog bites.
