Indigo Clinger

This modest-sized vine is a steady-growing plant, with the largest known specimen reaching a length of 36 feet (11.0 meters) and growing as high as 104 feet (31.7 meters).

It takes 4 years for the orange stems to mature, by which point they have tangled themselves into thick mats with a diameter of 5 inches (13 cm) and are smooth and rubbery.

The asymmetrical, smooth leaves reach up to 9 inches (23 cm) in length. They are green on the sides and indigo at the center, and have smooth edges.
