Occurrence

The distribution area of Utricularia ochroleuca extends from Europe to Afghanistan, from Far Eastern Asian Russia to Japan and from sub-Arctic America to the western and northern United States. The pale yellow water hose avoids lime and grows in Germany in oligo- to mesotrophic waters such as ponds and gullies, especially in raised bogs . In Central Europe it is a character species of the Sphagno-Utricuralreitum ochroleuci from the Sphagnno-Utricularion association. He likes to appear in Rhynchosporion Schlenken together with Sphagnum cuspidatum . It occurs in water depths of 20 to 300 centimeters and more.

The species is rarely found in south-west Bavaria , south-east Baden-Württemberg ( Neukirch ), south Rhineland-Palatinate , North Rhine-Westphalia , north-east Saxony and Brandenburg . It is considered extinct in Lower Saxony and Schleswig-Holstein .
