Mimosa pudica — often called “dormilona” (sleepyhead!) in Costa Rica. 🌱

Fun fact: the folding response is called seismonasty — The folding happens because the plant quickly changes turgor pressure in special hinge-like cells at the base of the leaflet and petiole, causing them to collapse.

When you touch Mimosa pudica, the little paired leaflets fold upward toward each other along the midrib, like two hands closing.

One of the coolest plant tricks — and why kids in Costa Rica love playing with “dormilona!” 😄
