Lysichiton americanus Hultén & H. St. John grows in the transition zone of terrestrial, semi-aquatic and aquatic habitats like swamps, fens, wet meadows, marshy and alluvial woodlands, along streams, riverbanks, lakesides and ponds. It has no specific site condition requirements except the presence of saturated organic soils. It is often found in protected semi-natural habitats. Lysichiton reproduces almost exclusively by seeds, which may be dispersed downstream along waterways. However, spread by natural means is not frequent and rather limited. L. americanus has become established locally in swamp forests and associated wetlands in the EPPO region (resulting most of the time from plantation in the site). After some years, its huge leaves build a dense layer excluding light from native species which are usually not adapted to extreme darkness. It can displace and cause local extinction of rare species of mosses and vascular plants (Carex echinata, Viola palustris, and orchids). (Branquart et al. 2010).
