Silvervine

This average-sized vine is a steady-growing plant, with the largest known specimen reaching a length of 25 feet (7.6 meters) and growing as high as 829 feet (252.7 meters). It prefers to grow on rock formations.

It takes 18 months for the copper stems to mature, by which point they have often fused together into ropes with a diameter of 3 inches (8 cm) and are smooth and rubbery.

The very thin, fuzzy leaves reach up to 1.0 foot (30 cm) in length. They are found in silver and silver varieties, and have jagged edges.
