Yellowvine

This modest-sized vine is a steady-growing plant, with the largest known specimen reaching a length of 32 feet (9.8 meters) and growing as high as 53 feet (16.2 meters).

It takes 3 years for the yellow stems to mature, by which point they each have a diameter of 2 inches (5 cm) and are soft and flexible.

The spear shaped, clammy leaves reach up to 1.6 feet (48 cm) in length. They are dull green and slate, and have smooth edges.
