We've all heard of shy people before, but what about a shy plant? As crazy as it may sound, one actually exists. It's called the Mimosa pudica, from the Latin word meaning "sensitive plant." It's also known as the touch-me-not.
The Mimosa pudica is native to South and Central America. It is a creeping annual or perennial herb, which means that it slowly expands across any surface it is attached to. However, the Mimosa pudica's real claim to fame is its strange reaction to being touched. If someone touches the leaves of the Mimosa pudica, the leaves immediately fold up. This gives people the impression that the Mimosa pudica is more of an animal than a plant.
The Mimosa pudica's reaction is the result of a chemical that is released whenever the plant is touched. The chemical makes water within the plant move toward the stem, and the plant's leaves fold inward as a result. Some scientists believe that this strange reaction is actually meant to be a form of defense against plant-eating animals.
It's not movement that makes the Mimosa pudica the most incredible plant in the world. Its leaves can also be ground up and used to treat several diseases. In Indian traditional medicine, the Mimosa pudica is used to treat swollen glands, and it is used to ease body pain and kidney disease in the Democratic Republic of the Congo. In fact, wherever the Mimosa pudica is found growing, there is usually a native culture that uses the plant to cure some kind of disease.
If you're fascinated by the idea of a moving plant, you don't need to worry; the Mimosa pudica is not a threatened species. In fact, it's the total opposite. The Mimosa pudica is listed in the global database of invasive species. An invasive species is one that has been moved to a new habitat and is destroying the local species. Even though the Mimosa pudica originated in the Americas, it has spread to Africa, South Asia, the Pacific Islands, and Australia. In many of these countries, it is viewed as a big problem.
