Climbing fern

Climbing ferns were a species of fern native to the moon Yavin 4. There, they grew alongside grenade fungi and bioluminescent orchids in the moon's Massassi tree forests.

Behind the scenes
Climbing ferns were first mentioned in Galaxy Guide 2: Yavin and Bespin, a Star Wars Legends supplement for West End Games' Star Wars: The Roleplaying Game which was written by Jonatha Ariadne Caspian and released in 1989. The fungus was confirmed to be canon by the reference book Ultimate Star Wars, which was released in 2015.
