Brief description

Amorpha fruticosa L. originates from North America and is cultivated as an ornamental. It was introduced in Europe from France to Russia (EPPO 2022). The fast-growing, deciduous shrub grows preferentially in wetlands, like riparian and alluvial habitats, sandy banks of ravines, coastal areas, and dunes. However, it tolerates some disturbed areas, such as plantations, orchards, meadows and urban areas. Due to its high reproductive capacity, A. fruticosa can form dense thickets that outcompete native flora, change successional patterns and reduce biodiversity. It is now generally accepted to be among the most invasive alien species in Europe. Repeated cutting and mowing can help to control populations of this species (CABI 2022). 

In 2014, Switzerland added the Fabaceae to its List of Invasive Alien Plants (EPPO 2022).

Status and distribution in Luxembourg
