Copperfern

This massive creeper is a very slow growing plant, with the largest known specimen reaching a length of 2,728 feet (831.5 meters) and growing as high as 447 feet (136.2 meters).

It takes 38 years for the copper stems to mature, by which point they often have a diameter of 1.7 feet (51 cm) and are smooth and fuzzy.

The wispy, smooth leaves reach up to 2.3 feet (69 cm) in length. They are found in slate and cream varieties, and have ripped edges.

During late spring, the creeper produces many large beige flowers.
