Ambervine

This large vine is a steady-growing plant, with the largest known specimen reaching a length of 62 feet (18.9 meters) and growing as high as 101 feet (30.8 meters).

It takes 4 years for the lime green stems to mature, by which point they have often fused together into ropes with a diameter of 1.1 feet (33 cm) and are rough and gnarled.

The pleated, leathery leaves reach up to 1.3 feet (38 cm) in length. They are solid blue or amber, with violet lines, and have wavy edges.

During late spring, the vine produces lots of large light brown flowers.
