Ostrich fern
Matteuccia struthiopteris
A spectacular tall vase-shaped native fern with broad upright sterile fronds (resembling ostrich plumes — hence the name) and distinctive contrasting fertile fronds that emerge brown + persistent through winter. The traditional edible fiddlehead source — young curled fronds harvested in early spring are sold seasonally as a delicacy. Spreads vigorously via rhizomes in moist soils; provides good groundcover-scale presence.
Native: 24 US states + 5 CA provinces
