Shadowvine

This enormous creeper is a very slow growing plant, with the largest known specimen reaching a length of 2,554 feet (778.5 meters) and growing as high as 730 feet (222.5 meters).

It takes 2 years for the black or slate stems to mature, by which point they can reach a diameter of 2.9 feet (89 cm) and are smooth and waxy.

The spear shaped, soft leaves reach up to 3.7 feet (1.1 meters) in length. They are solid brown with white splotches, and have wavy edges.

During late spring, the creeper produces lots of small purple flowers.
