Crystal Fern
these silicon-based crystalline formations are strange, transparent growths that are found in some asteroid belts. The best crystal fern specimens have been found in the Hoth asteroid belt, where they have been known grow between neighboring asteroids. The average fern is several meters in height. When conditions are right, they can continue to grow outward, forming tangled webs. The ferns' ability to grow like this, spanning asteroids, has led to theories that the fern is an actual lifeform. The crystal ferns are sought by collectors, scientists, and profit-seekers, although they are incredibly hard to harvest without causing major damage to their structure.
