Rubus argutus is a North American species of prickly bramble in the rose family. It is a perennial native to the eastern and south-central United States from Florida to Texas, Missouri, Illinois, and Maine. Common names are sawtooth blackberry or tall blackberry because of its habit of growing up to 2 meters (80 inches) in height.
The flowers are white with large petals, borne in mid-spring.
