Mimosa pudica also called sensitive plant, sleepy plant, action plant, touch-me-not, or shameplant.
Lajjalu is a small, creeping annual or perennial herb that is native to South and Central America but is now found in various parts of the world. It is characterized by its sensitive compound leaves, which fold inward and droop when touched, shaken, or exposed to heat or light—a phenomenon known as “thigmonasty.” The plant typically produces pink or purple flowers and small, pod-like fruits.
