Life History and Reproduction: Skunk cabbage has a remarkable ability to produce heat that allows it to emerge and bloom even when the ground is still frozen. During the winter when temperatures are freezing, the flower buds can warm up to 70 degrees, which melts the snow around the plant. Pollinated flower heads develop berry-like fruits containing seeds which germinate into new skunk cabbages next growing season. Skunk cabbage leaves decay rather quickly. The leaves have high water content, so there is less plant matter to dry out and decompose.
