Riverbank Grape is a North American grape and one of the hardiest species in the world surviving temperatures as low as minus -40F. It is a stunning vigorous climbing vine, up to 50 feet, with variable 3 to 7 inch leaves (rounded or deeply lobed) displaying beautiful gold and red autumn colors. It usually climbs trees, shrubs or fence rows, but will rise only 1/2-2 feet above the ground while sprawling in open areas. The blooming period occurs during the late spring and lasts about 2 to 3 weeks. The small greenish-white or greenish-yellow flowers have 5 tiny petals, and a fragrant musky scent. The flowers are replaced by 1/4 to 1/2 inch black fruit in clusters to 6 inches that develop during the summer. The grapes are sweetly acidic and have a lovely flavor when allowed to fully ripen on the vine, thus excellent for winemaking and jellies. Highly valued by wildlife and perfect for naturalizing woodland areas or along fences and of course as root stock.
