Dewberry
Dewberry, a trailing shrub closely related to the blackberry. It is characterized by canes, or prickly stems, that trail along the ground. The dewberry is native to North America and grows in nearly every part of the United States.
The dewberry vine is slender and generally hugs the ground as it grows, shooting out tendrils in several directions. The leaves are shiny and leathery and have blunt-toothed edges. The flowers are white. The fruit, which is edible, is dark reddish-black and is larger than that of the common blackberry.
Dewberries belong to the rose family, Rosaceae. The American dewberry, the most common species, is Rubus flagellaris.
Dewberry fruit is dark red-black and larger than the blackberry.
