Onoclea sensibilis dwells in a variety of wet swamp and wood habitats: wet meadows, thickets and bogs, as well as stream and riverbanks and roadside ditches.
It grows best in a shaded or partially shaded area in a moist soil. The plant can tolerate dryer conditions in shade, and will tolerate wet soils and so occurs in soggy ground or at the very edge of water in shade or sun. Sensitive ferns spread to form colonies and are often the first species to inhabit disturbed areas. They can become weedy if not sited properly.
