Caramel Blackvine

This average-sized bine is a steady-growing plant, with the largest known specimen reaching a length of 44 feet (13.4 meters) and growing as high as 111 feet (33.8 meters).

It takes 17 months for the gray-green stems to mature, by which point they have tangled themselves into thick mats with a diameter of 5 inches (13 cm) and are hard and brittle.

The asymmetrical, clammy leaves reach up to 9 inches (23 cm) in length. They are caramel on the edges and black at the center, and have jagged edges.
