Importance and distribution in Luxembourg

Distribution map of Impatiens parviflora DC. in Luxembourg. Recorder-LUX & iNaturalist, 2019.08.21.

The species was first documented in Luxembourg in June 1956 on the right bank of the river Attert in the municipality of Redange (Reichling 1958). However, the herb is so widespread in Luxembourg’s forests that its presence seems natural and it is thus seldom reported. This explains why by 2012 only 81 observations of the species in Luxembourg were listed in the Recorder database, even though I. parviflora is found in most forest areas in Luxembourg.

Most of the current 358 observations in the database (18/01/2018) have been collected during systematic inventories along the main watercourses in 2013. The actual distribution map for the species is thus only a partial indication of its real distribution in Luxembourg since indications of most of the numerous populations in forest areas are missing.

Two other alien balsam occur in Luxembourg, the invasive Himalayan Balsam (Impatiens glandulifera), which is widespread in riparian ecosystems and forests across Luxembourg, and Balfour’s touch-me-not (Impatiens balfourii), first observed in 2016 in the wild in Luxembourg.

Small balsam is a herb that is widely dispersed in European forests. It prefers shaded and moist nutrient-rich stands, but can also grow in acidic conditions. It thrives in beech and alder forests, but can also be found in parks, along hedgerows, on forest edges, in waste grounds and ruderal habitats (Source:
