Bead Fern

Onoclea sensibilis (oh-no-KLEE-ah sen-si-BIL-iss)

Family: Onocleaceae Native Herbaceous (1-3 ft)

Sensitive fern is a large, deciduous, herbaceous perennial fern in the spleenwort family (Aspleniaceae) that thrives in moist woodland soils. It is native to both eastern North America (including North Carolina) and eastern Asia. The species epithet is Latin for “sensitive,” which along with the common name, sensitive fern, refers to the inability of this fern to tolerate mild frost or drought. Sensitive ferns prefer soils high in organic matter, clay or loamy soils that are consistently moist. These ferns thrive in shaded environments, protected from cold or drying winds. Propagation occurs both via creeping rhizomes and spores. These ferns exhibit long pinnatifid, sterile fronds, which have characteristic netted veins. The fertile fronds are less than half of the length of the sterile fronds and they turn brown as the summer progresses. This fern’s leaf color in the fall is gold/yellow and the leaves can be dried for indoor arrangements. Insects, Diseases, or Other Plant Problems: The foliage may deteriorate as summer progresses in hot climates, particularly if soils are not kept moist.

Leaf detail
The sensitive fern has broad, almost triangular fronds. The sterile fronds are deeply pinnatified to bipinnatified, and thin texture. The fronds of most pinnae are nearly opposite, the rachis is smooth, pale tan or yellow. The fronds turn yellow or russet in the fall. Fertile fronds emerge in late summer, are woody with beadlike segments, brown and persist into winter. Stipes are long (one half to two-thirds of frond), network veined. It is dimorphic (occurring in or representing two distinct forms).
