Interrupted Fern

Scientific name

Osmunda claytoniana


Interrupted Fern is a fern species that can grow up to 1 m in height. The leaves are green, are ascending and erect, are larger in the middle of the stem, and appear in a spreading form. The leaflets are deeply lobed, narrow, and lanceolate shaped. When the leaflets are fertile in the spring, they wither away leaving an interruption between the upper and lower leaflets, hence the common name. This plant spreads well and can be used to naturalize un-vegetated areas. The roots can be useful for controlling erosion and stabilizing shorelines.

Planting conditions

Interrupted Fern grows best in moist to wet conditions with shade or partial sun exposure. It prefers organically rich, humus, loam, or sand soil types. It can tolerate acidity, heavy shade, shallow soil, and rocky soil. This fern can be naturally found in shaded forests, on sandy slopes, around swamps or marshes, and along shaded stream or lake shorelines.
