English: This pink flower is the flower of a plant names Mimosa pudica commonly known as shame plant and Touch-me-not. This plant is commonly seen in the Caribbeans, South and Central America, South of USA states, East Asia, South Asia, Micronesia, Australia and South Africa. This plant got this names like shame plant and Touch-me-not because when we touch it's leaves the leaves would close because, many plants close up at night, usually to protect pollen or reduce water loss while the leaves aren't photosynthesising. But the Mimosa genus is a creeping shrub and highly attractive to grazing animals. ... Doing so reduced the leaf area presented to herbivores and made the plant look wilted.
