Ambervine

This colossal vine is a slow growing plant, with the largest known specimen reaching a length of 810 feet (246.9 meters) and growing as high as 997 feet (303.9 meters).

It takes 34 years for the gray and cream stems to mature, by which point they sometimes have a diameter of 3.5 feet (1.1 meters) and are rough and prickly.

The very narrow and elongated, soft leaves reach up to 1.9 feet (58 cm) in length. They are hazel on the edges and amber at the center, and have ripped edges.
