Calcareous sandy and gravelly shores, interdunal flats, meadows, stream banks, fens, and marshes.

This is our commonest and most widely distributed species in the state, and the latest to reach the peak of blooming. It also has the largest flowers and the largest leaves, although overlapping P. palustris in these parts. The leaf blades are as much as 4–5 (–5.8) cm wide, although more often ca. 2–3 cm (and sometimes all the leaves even smaller), and they are at most subcordate at the base.
