Have you seen the so-called sensitive plant or sleeping grass? When I was a kid, I always play in the garden. One time, I accidentally hit this plant with small leaves, then I saw them folding. They look like those kids who turn blush and become shy whenever they see they're crushes. Out of curiosity, I ran to my mom and asked about it. I found out from that its the sensitive plant or Mimosa pudica, a plant which is known for its leaves that fold when touched. Their leaves also fold during the evening. Mimosa genus is common in Southern Mexico and
Central America. However, this genus is widely cultivated as an indoor plant in temperate places and as an outdoor plant in the tropics.
