Occurrence

Locations of the low-lying Vergissmeinnicht are fresh Bach Staudenfluren , spring swamps , damp forests and warehouses corridors . Myosotis decumbens occurs in societies of the Adenostylion alliariae association or the association Rumicion alpini. In the Allgäu Alps, the species rises from the valley locations to an altitude of 1720 meters on the Grünten .
