Sunshinevine

This colossal bine is a very slow growing plant, with the largest known specimen reaching a length of 1,566 feet (477.3 meters) and growing as high as 995 feet (303.3 meters). It prefers to grow on trees.

It takes 48 years for the emerald stems to mature, by which point they sometimes have a diameter of 2.9 feet (89 cm) and remain soft and fleshy.

The wide, fuzzy leaves reach up to 2.7 feet (81 cm) in length. They are yellow on the sides and brilliant yellow at the center, and have smooth edges.
