Current situation of Lysichiton americanus in France

Lysichiton americanus (Araceae, EPPO A2 List) was reported for the first time in 1995 in the Loire Department (Haute Vallée du Furan, Pont Souvignet, in Bessat) in France, where it escaped from a garden. Except for this locality, the species remained confined to gardens in France, but in 2005, the plant also escaped in the Haute-Vienne Department. The species was found on Saint-Léonard de Noblat (Ancien Moulin du Repaire) and developed in the understorey of a Salix acuminata (Salicaceae) forest.
Four plants of L. americanus were observed in 2005 and the population expanded to 12 plants in 2006, thus confirming that the species can thrive at this location.
It was observed in the Haute-Vienne Department that each plant could develop 3 to 4 inflorescences.
