A Detailed Guide to Propagating Mimosa pudica (Sensitive Plant) from Seed
A notable feature of Mimosa pudica (sensitive plant) is that its leaves are extremely sensitive and capable of thigmonastic movement: a light touch with the hand makes the small leaflets immediately fold together from left to right; with a firmer touch, even the pinnae and the petiole droop down at 60 degrees. At night it likewise assumes a dormant, drooping posture, and it shows the same response to sudden cold or electrical stimulation.
