Onoclea sensibilis (Sensitive Fern)

A unique addition to a moist woodland garden, Onoclea sensibilis (Sensitive Fern) is a deciduous, rhizomatous fern boasting broad, deeply pinnatifid, pale sea-green, sterile fronds, 2-4 ft. long (60-120 cm), adorned with leathery, triangular leaflets and netted veins. Shorter and narrow, the fertile fronds, 12 in. (30 cm), appear in mid to late summer, with bead like sori (spores) arranged toward the top of the fronds. The fertile fronds turn brown in late summer and persist throughout winter, releasing their spores to the wind the following spring before new leaves emerge. The common name comes from the observation by early American settlers that Onoclea sensibilis was very sensitive to frost, the fronds dying quickly when first touched by it. Easy to grow in most cool, moist, shaded sites, Sensitive Fern is a great asset for bog gardens, pondside plantings and water gardens. Cut fronds are great for dried flower arrangements.
