Greyvine

This average-sized vine is a steady-growing plant, with the largest known specimen reaching a length of 34 feet (10.4 meters) and growing as high as 620 feet (189.0 meters).

It takes 11 months for the drab yellow stems to mature, by which point they can have a diameter of 5 inches (13 cm) and are hard and brittle.

The wispy, waxy leaves reach up to 1.7 feet (51 cm) in length. They are found in grey, brown and black varieties, and have jagged edges.
