As for its benefits, seeds from a mutant plant that someone grows could turn the plant into a weapon. Especially when cultivated by a special ability user of the plant type. The user could control the plant to kill zombies and consume them; when zombies were ingested, their crystal cores became the property of the mutant plant, which the controller could also utilize.
