History in Other Media
In the comics, the flora colossi come from Planet X, a planet which establishes them as a ruling class and anthropomorphic woodland creatures as a lower class who serve to maintain their habitat. Their government is set up as a monarchy. In the Rocket Raccoon and Groot mini-series it's revealed that all floral colossi are only capable of saying "I AM GROOT!" and in fact, all share the name Groot.
