Symplocarpus foetidus, skunk cabbage, eastern skunk cabbage, clumpfoot cabbage

Skunk Cabbage is remarkable in that it is able to generate heat when the ground is frozen. In fact, its flowers can warm up to around 70º F. This allows the plant to emerge and bloom when most other spring-blooming species are still dormant. The root and underground stem (rhizome) are used to make medicine. The pungent smelling roots of the skunk cabbage have been a popular conventional cure for bronchitis, tight coughs, and phlegm or catarrh. Several herbal medical practitioners recommend the skunk cabbage to treat nervous disorders as it is said to have a moderate sedative or tranquilizing properties. In earlier times, an indigenous tribe of America also inhaled in the aroma of the mashed skunk cabbage leaves to get relief from headaches.

Plant Description

Skunk cabbage is a low-growing, foul-smelling tuberous plant that grows about 30-90cm (1-3ft) tall. The plant is found growing in swamps, wet woods, along streams, and other wet low areas and normally prefers moist, wetland soil. Roots are fleshy, contractile and rhizome is usually two inches or little more in length and measures one inch in diameter and 30 cm (1 ft.) thick. Skunk cabbage rhizomes are found in slanting slivers that are compacted and ridged. The rhizomes have a dark brown hue on the exterior and are white or yellowish inside.

Leaves

Eastern skunk cabbage has leaves that are very large entire margined with a plastic-like appeal, and have a slight wrinkle, about 40–55 cm (15.75–21.5 in) long and 30–40 cm (12–15.75 in) broad. It flowers early in the spring when only the flowers are visible above the mud. The stems remain buried below the surface of the soil with the leaves emerging later. The flowers are produced on a 5–10 cm (2–5 in) long spadix contained within a spathe, 10–15 cm (4–6 in) tall, and mottled purple in color.

Flower & fruit

As the spathe gets bigger, it will reveal another part inside, called a spadix. The spadix is a little knob covered with small flowers. Numerous small, purple flowers grow on a small, oval, fleshy spike (or spadix), covered by a purple and yellowish-green, hood-like bract (or spathe). Flowering time is from February to April before the leaves appear. The whole plant emits a skunk or garlic odor. The plant bears oval-shaped fruit that is green when young turning to black as they mature. The fruit has wrinkled outer skin and whitish flesh.
