Eastern Skunk Cabbage

Symplocarpus foetidus (sim-plo-KAR-pus FET-uh-dus)

Family: Araceae Native Herbaceous (3-15 ft)

Skunk Cabbage is a perennial herb in the Araceae family with large, heart shaped foliage. Its name originates from its appearance, Symplocarpus translating to 'connected fruits', while foetidus refers to the plant's unpleasant odor. Its flowers, which appear before the leaves, are small and form in a greenish-yellow spadix or spike surrounded by a red-purple-brown spathe or sheath. The flowers have the ability to chemically heat themselves giving the plant the ability to melt its way through snow, earning the recognition as the first flower of spring. Although they are attractive and bloom early, the flowers as well as the leaves have a foul smell if bruised. This odor is said to have the scent of decaying flesh which lures insects who pollinate the plant. Typically found in bogs, swamps, wet meadows, and very wet woods its native habitat includes swamps and muddy locations. Once planted, its roots firmly take hold, making transplanting extremely difficult. Its future may be threatened by the decline in wetlands in some locations. Insects, Diseases, and Other Plant Problems: No serious issues with diseases or insects.
