Skyvine

This enormous bine is a very slow growing plant, with the largest known specimen reaching a length of 1,581 feet (481.9 meters) and growing as high as 865 feet (263.7 meters).

It takes 29 years for the silver stems to mature, by which point they often have a diameter of 9 inches (23 cm) and are smooth and slick.

The very thick, smooth leaves reach up to 3.5 feet (1.1 meters) in length. They are generally sky blue, and have toothed edges.

During late spring, the bine produces many large dark purple flowers, and during the mid-summer, after flowering, it produces copious amounts of tiny berries.
