Originally, from North America, the common ragweed is considered as an invasive alien species in Central Europe. In addition, this ambrosia produces a very allergic pollen. It prefers disturbed habitats, for example it can be found in surfaces such as construction sites. The common ragweed has some characteristics that allow its identification, however it can be confused with other species such as the common mugwort.
