In Germany, the high bedstraw occurs very scattered or rarely. Among other things, it is missing in the north over large stretches. In Austria this species is also quite rare and in some areas, for example in the Alps, classified as endangered. In Switzerland, Galium elongatum occurs almost only in the north of the area.

The high bedstraw grows in swamps and on the banks of waters. It prefers wet, nutrient-rich and often peaty clay and swamp humus soils. It thrives in Central Europe in companies of the Alnion and Magnocaricion associations.
