The plant’s most fascinating feature is the fern-like leaves that close and fold up when touched. This reaction is known as a sesimanastic movement, or a physical reaction to shock. During the hours of darkness the leaves also close as a reaction to the absence of light. This is known as nyctonastic movement. The plants common name derives from the sensitivity to outside stimuli.
