Silvervine

This big vine is a steady-growing plant, with the largest known specimen reaching a length of 98 feet (29.9 meters) and growing as high as 100 feet (30.5 meters).

It takes 4 years for the yellow-green stems to mature, by which point they can have a diameter of 8 inches (20 cm) and are smooth and rubbery.

The very thin, soft leaves reach up to 2.3 feet (69 cm) in length. They are turquoise on the edges and silver at the center, and have ripped edges.

During late spring, the vine produces many clusters of large crimson flowers.
