Coppervine

This big vine is a steady-growing plant, with the largest known specimen reaching a length of 160 feet (48.8 meters) and growing as high as 67 feet (20.4 meters).

It takes 20 months for the gray-green stems to mature, by which point they each have a diameter of 1.5 feet (46 cm) and are rough and prickly.

The spear shaped, covered in fine hairs leaves reach up to 1.8 feet (53 cm) in length. They are grey on the sides and copper at the center, and have jagged edges.

During late spring, the vine produces dozens of giant cyan flowers.
