Emerald

This massive bine is a very slow growing plant, with the largest known specimen reaching a length of 1,161 feet (353.9 meters) and growing as high as 926 feet (282.2 meters).

It takes 46 years for the emerald stems to mature, by which point they often have a diameter of 2.3 feet (71 cm) and are smooth and woody.

The stiff, pointed, leathery leaves reach up to 2.2 feet (66 cm) in length. They are either beige or aquamarine, with deep blue patches, and have jagged edges.

During late spring, the bine produces handfuls of large deep blue flowers.
