Moist sandy shores and excavations (“borrow pits”); peaty bog margins and disturbed trails.
Depauperate plants of H. majus, such as seedlings blooming the first year, may resemble this species and are often thus misidentified. The sepals of H. majus attain a greater length, especially in fruit. Both species have very reduced, subulate ultimate bractlets in the inflorescence, as in H. mutilum.
