- "Ah. Aha, crystal ferns. I have heard of them in other asteroids. Some prospectors search for them. They are quite fragile and therefore are considered great treasures."
- ―Tenel Ka Djo
Crystal ferns were plants believed by some to be primitive silicon-based life-forms. The fern could be found in the Hoth asteroid field. It could grow up to several meters in height and propagated when shards of crystal were broken off and took hold on another asteroid.
