Symplocarpus foetidus, the plant known in English as skunk cabbage and whose Japanese name, Zazen-sou, means Zen meditation plant, has a property of which a Zen master would be proud: it can maintain its temperature as high as 20 °C, even on a freezing cold day. Unlike animals, which generate heat throughout their bodies, the skunk cabbage makes most of its heat through metabolic processes in the spadix, the plant's central spike-like flowering stalk.
Takanori Ito and Kikukatsu Ito at Iwate University in Japan have monitored the temperatures of the spadix in wild skunk cabbages to understand the dynamics of this temperature control. They found that a phase space plot of temperature at separated times is a strange attractor, which they refer to as a Zazen attractor. This is the first demonstration of deterministic chaos in a higher plant.
