A total of 16 photos of grape vines (Vitis) are displayed in this gallery. Grape vines produce the grapes that are sold in grocery stores. These berries form in clusters on the vine and contain a powerful antioxidant called resveratrol. Resveratrol is found in higher concentrations in darkly colored grapes, particularly the muscadine variety. The leaves of the vines are alternate and have been used in traditional medicine to treat disorders of the pancreas and heart.
