Caramel vine

This modest-sized vine is a steady-growing plant, with the largest known specimen reaching a length of 33 feet (10.1 meters)0.

It takes 5 years for the brown stems to mature, by which point they sometimes have a diameter of 3 inches (8 cm) and are rough and gnarled.

The oval-shaped, leathery leaves reach up to 1.3 feet (38 cm) in length. They are caramel and dark grey, and have tattered edges.

During late spring, the vine produces dozens of average subtle green flowers.
