Mimosa pudica

This is my new favourite thing, a plant my Dad gave me called Mimosa pudica.

mimosa-before

M. pudica is also known as the “sensitive plant” or “touch-me-not” because it reacts to touch. When touched its leaflets quickly close up.

mimosa-after

Nobody’s really sure why M. pudica has evolved this response. It exhibits the same behaviour at sunset, reopening its leaflets in at sunrise the next morning.
