Zizania

From the Latin Zizania, referring to a type of wild grain or weed mentioned in the biblical parable of the wheat and tares, suggesting wild, untamed natural growth.

Zizania comes straight from the pages of the Bible — it's the word used in the parable of the wheat and tares (Matthew 13) for the weed that grows among the good grain, as well as a genus of wild aquatic grasses. For a pet it's a gloriously unusual choice, the kind of name that makes botanists and theologians do a double-take. There's something appealingly wild and untamed about it — a female pet named Zizania is probably a little bit feral in the best possible way.
