Sensitive fern varies in height from a few inches to more than 3 ft. Its sterile fronds, which wither early, are light to brown-mottled green and deeply cut into long lobes which almost reach the stem. Twice-pinnate fertile fronds appear in late summer and, though dead, remain upright through winter. Fiddleheads appear in the spring in shades of pale red. The roots colonize but are usually shallow, though hefty. The stalks of this fern are said to have a decorative, "beaded" appearance, lending the plant one of its common names, Bead Fern.

Onoclea sensibilis, the sensitive fern, also known as the bead fern, is a coarse-textured, medium to large-sized deciduous perennial fern. The name comes from its sensitivity to frost, the fronds dying quickly when first touched by it. It is sometimes treated as the only species in Onoclea, Kang, Sang-Wook; Kim, Jung-Lye; Kwon, Gyoo Taik; Lee, Yong-Jin; Park, Jung Han Yoon; Lim, Soon Sung; Kang, Young-Hee (November 2011).

Sensitive Fern has distinctive, coarsely lobed leaves of a slightly chartreuse color. A good native fern for clay soils, it grows best in partial or full shade, in moist settings. It also does very well in average garden soils, as long as there is consistent moisture and the soil is not allowed to dry out. In optimal conditions Sensitive Fern spreads quickly by rhizomes, making it an excellent ground cover plant for low moist areas. The name, Sensitive Fern, refers to the tendency of the leaves to die-back with the first frost. Rabbit and deer resistant.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). (Source: plants.ces.ncsu.edu)
