India! I'm from Visakhapatnam, a major port city with beautiful beaches, surrounded by mountains. It is the only natural harbor on the East Coast of India.

The touch-me-not plants or Mimosa Pudica (as I know them now, thanks to you) grew everywhere in India. I don't see them much now. In fact, this plant was considered a weed for a long time and is only now being appreciated for its medicinal properties.
