Bluevine

This huge vine is a slow growing plant, with the largest known specimen reaching a length of 1,108 feet (337.7 meters) and growing as high as 203 feet (61.9 meters).

It takes 7 years for the lime green stems to mature, by which point they each have a diameter of 4.9 feet (1.5 meters) and are smooth and woody.

The broad, flat, clammy leaves reach up to 2.0 feet (61 cm) in length. They are found in deep green and blue varieties, and have rounded edges.
