Lysichiton americanus Hulten & H. St. John Fam: Araceae American Skunk-cabbage Ecology: American Skunk-cabbage can grow in both shallow water or on very moist soils such as stream sides in forests and wet woodlands; which are found to be particularly suitable. It develops both in sunny and in shaded locations, but the latter will result in fewer inflorescences developing. A large amount of seed is produced that remains viable for at least six years. Threat: Unlike most invasive plant species, American Skunk-cabbage can establish in more or less undisturbed habitats such as swamp forests. Seeds can disperse downstream and form dense populations displacing native plants. However, the American Skunk-cabbage is a slow-growing plant and can subsequently be easily controlled. Control: American Skunk-cabbage is easily eradicated by cutting off the plants below ground level. Monitoring is necessary as there may be a seed bank. Identification / similar species: American Skunk-cabbage is very similar to Asian Skunk-cabbage. American Skunk-cabbage has a strong smelling, yellow inflorescence and leaves that emit a foul odour when crushed. In contrast, Asian Skunk-cabbage has a white, odourless inflorescence and the leaves have no smell when crushed. Asian Skunk-cabbage is also planted along ponds, but is not naturalized in the Netherlands.
