Internal heating

There is a widespread family of plants known as the arums—containing many thousands of species—which create heat in the flowering structures by burning up sugars, to vaporize certain chemicals that attract flies to come and pollinate the flowers. The most proficient of these self-heating plants seems to be the skunk cabbage (Symplocarpus foetidus), which grows in swamps in North America, creating quite a stink with the chemicals that it evaporates.The amount of heat released by a skunk cabbage can raise the temperature inside its flowering head to 35°C (almost as warm as the human body temperature), even when the air temperature is below freezing. Early in spring, when snow is still on the ground, the skunk cabbage flower heads are able to melt the snow around them, poke up and flower before any other species.
