Mimosa pudica

Sensitive Plant

"Sensitive Plant", so called because the leaflets fold up in a most spectacular manner when touched or blown by the wind. Run your hand over the plant and the leaves will fold up and the leaf stalk will drop as if on a hinge. The movements are quickest with young plants in bright sunshine. They return to their normal condition in a few minutes. More info
