Also known as the ‘Shy Plant’, ‘Humble Plant’, ‘Sleeping Grass’, ‘Touch-Me-Not’, ‘Sensitive Plant’ and ‘Modest Princess’, the Mimosa pudica reacts to touch as if it is indeed ‘shy’. Native to South and Central America, it’s actually now considered a ‘pantropical weed’. Still, its reaction to touch makes it a bit more anthropomorphic than your basic potted pathos.
