Mimosa pudica
Mimosa pudica (from Latin: pudica "shy, bashful or shrinking"; also called sensitive plant, sleepy plant, action plant, Dormilones, touch-me-not, shameplant, or shy plant) is a creeping annual or perennial flowering plant of the pea/legume family Fabaceae and Magnoliopsida taxon, often grown for its curiosity value: the compound leaves fold inward and droop when touched or shaken, defending themselves from harm, and re-open a few minutes later. This reflex may have evolved as a defense mechanism to disincentivize predators, or alternatively to shade the plant in order to reduce water lossage due to evaporation. The species is native to South America and Central America, but is now a pantropical weed. It can also be found in Asia in countries such as Bangladesh, Thailand, India, Nepal, Indonesia, Malaysia, Philippines, Vietnam, Cambodia, Laos, Japan, Sri Lanka, Guam and well across the southern part of the United States.
