Indigo vine

This big vine is a steady-growing plant, with the largest known specimen reaching a length of 302 feet (92.0 meters) and growing as high as 94 feet (28.7 meters).

It takes 4 years for the emerald stems to mature, by which point they each have a diameter of 8 inches (20 cm) and are smooth and waxy.

The long, narrow, fuzzy leaves reach up to 10 inches (25 cm) in length. They are muted purple and yellow, and have rounded edges.

During late spring, the vine produces hundreds of average indigo flowers, and during the early autumn, after flowering, it produces a few tiny berries.
