Mimosa pudica, commonly known as the sensitive plant or touch-me-not, is a fascinating plant known for its rapid leaf movement in response to touch. Native to South and Central America, it thrives in warm climates, bright, indirect sunlight and well-draining soil, requiring consistent moisture without becoming waterlogged. It performs best in high humidity environments and should be protected from direct, harsh sunlight. This plant has been noted for its air purifying qualities, but it should be handled with care as it can be irritating to sensitive skin and is toxic to people and pets if ingested..
