The association Calystegio-Impatientetum is dominated by Impatiens glandulifera, a tall annual herb, which is an invasive neophyte of Asian origin. A constant subdominant species is Urtica dioica. This vegetation type commonly occurs on river banks and in floodplains; less frequently it can be found in wet ditches, along forest roads or in wet waste places. Habitats are usually partially shaded, with wet loamy to loamy-sandy soils rich in nutrients. In the Czech Republic Impatiens glandulifera has been spreading since the end of the 19th century. Currently it is common along rivers in lowland and colline areas throughout the country.
