Gardeners' Notes:


On Feb 12, 2005, melody from Benton, KY (Zone 7a) wrote:

The common name refers to the skunk-like odor of the sap and the fetid aroma of the flowers, which draws flies as pollinators.

The sap was once used as treatment for ringworm, the short, fleshy underground stem is eaten by animals. Baked, it supplimented the winter diets of the Native Americans.

Lysichiton americanum, aka Skunk Cabbage, or Swamp Cabbage, is native to the Pacific Northwest of the United States. The botanical names is roughly translated to "Loose Tunic" refering to the bright yellow spathe (petal-like bract) around the spadex (flower spike). Skunk cabbage emerges from swampy areas in early spring, and as the season progresses, the net-veined leaves can reach to 5 ft in length, bearing a swampy odor. This plant is a tasty treat for bears. It can be introduced to the garden in wet ground by division or seed.
