Coefficient of Wetness:
Common in swamps, ravines and hollows in beech-maple forests, floodplains and bottomland, stream borders, etc., in the southern half of the Lower Peninsula. Northward, generally very local (except on islands in the Great Lakes) and often in coniferous swamps. Colonies of skunk-cabbage ascending wooded slopes and sides of ravines indicate the presence of seepage springs.
The familiar flowering spadix with its strong odor and hooded spathe is the first wildflower of the spring, often blooming through the snow (and producing heat to melt snow and ice and presumably warm the interior for the pollinators comfort; see Seymour (1997)). It is followed by development of the large leaves which, especially when bruised, also produce the odor. The large, knobby black fruit matures in late fall, when plants are leafless, and is often not recognized as belonging to skunk-cabbage.
This remarkable plant has contractile roots that pull its long, trunk-like rhizome into the ground as growth proceeds; the lower portion gradually rotting away as the plant ages. Plants appear to reach great age, most effusively expressed by Shull (1924): "…the Skunk Cabbage that is seen today growing in unpretentiousness in any bog may possibly outrival the sturdiest of the oaks in point of age, may not improbably have occupied that very spot long years before Columbus set foot upon our shores and may continue there a thousand years and more from now if only the fates be kind."
