A perennial herb of wet places on the margins of lakes, rivers, streams and canals, and in ditches, marshes and wet woodlands. Lowland.
The distribution of S. auriculata is broadly similar to that in the 1962 Atlas. There are rather more records at the northern edge of its contiguous range, probably because of more thorough recording in previously under-worked areas. Many records from N. Scotland have been discounted as errors for S. nodosa.
Suboceanic Southern-temperate element.
