Blackthorn Creeper

This big creeper is a steady-growing plant, with the largest known specimen reaching a length of 304 feet (92.7 meters) and growing as high as 122 feet (37.2 meters).

It takes 11 months for the moss green stems to mature, by which point they can reach a diameter of 1.3 feet (38 cm) and are rough and prickly.

The broad, flat, waxy leaves reach up to 2.7 feet (81 cm) in length. They are generally black, and have toothed edges.
