description
The rust-red vine is a shrub that climbs up to 25 meters with red-brown felted shoots. Tendrils or inflorescences are missing on every third shoot node. The leaves are divided into leaf blade and petiole. The leaf blade is simple, 20 to 30 centimeters wide, rounded-egg-shaped, more or less clearly three to five-lobed with a deep heart-shaped base and a narrow stalk bay. The leaf margin is provided with short, spiky teeth. The upper side of the leaf is dull green, wrinkled and almost bare, the underside is rusty-red, spiderweb-like and tomentose, especially along the leaf veins. The autumn color is strikingly scarlet to carmine.
The flowers are arranged in 6 to 12 centimeters long, narrow and rust-red felt-like panicles . The fruits are black and purple and have a diameter of about 1 centimeter.
The rust-red grapevine blooms from June to July.
The number of chromosomes is 2n = 38.
