"If you sing or talk to the plant in a high, gentle voice (saxophone or violin works even better), the smaller leaves will begin making subtle back-and-forth motions; sometimes quick, sometimes slow." - Lonely Planet Thailand
OK, the video isn't that great and the movement isn't that noticeable but I think it's still awesome. The movement is not from wind or sleight of hand.
The flowers have all been removed from the plant to prevent anyone from stealing them and breeding these flowers elsewhere. It is a hybrid of Codariocalyx Motorius Ohashi Leguminosae.
The plants are most active from November to February - the cool season - and between 7am and 10am or 4:40pm and 6pm. *Lonely Planet Thailand
