Exotic plant

Non-terrestrial plants (sometimes called exotic plants) are any alleged flora unacknowledged by mainstream botany, found in extraterrestrial habitats or other inaccessible places (from the point of view of most humans on Earth) such as hidden bases, ancient arcs, and cryptoterrestrial milieus. Non-terrestrial plants range from virtually indistinguishable from terrestrial plants to having unusual characteristics, such as bearing unknown fruit types described in some "cosmic disclosure" accounts as possessing unique flavors, medicinal properties, or even discernable sentience.

Some reports suggest these plants thrive in underwater bases or underground civilizations, while others describe their existence in extraterrestrial ecosystems. Although any such flora could be classified as "exotic" in the sense of having implications that extend beyond the range of mainstream acknowledged botany, whether some or all of them could be classified as exotic beings may depend on whether they are considered conscious or sentient.
