The species was first documented in Luxembourg in 1937 and is widely spread by now. It was first found on 31st August 1937 in Hollenfels, municipality of Tuntange (Beck et al. 1950). 125 observations are listed in the Recorder database.

Elodea canadensis is an aquatic plant that thrives in a variety of freshwater habitats, from still to slow-flowing systems and from very shallow to deep waters. It is most frequent in clear, nutrient-rich and alkaline waters. Elodea aggressively invaded the waterways of Europe in the 19th Century (Source: http://ias.biodiversity.be/species/show/56).
