5 Tennessee Ostrich Glade Fern Matteuccia Struthiopteris Rhizome Root.

5 Tennessee Ostrich Fern rhizome/roots. Ostrich Fern is a clump-forming, upright to arching deciduous fern which typically grows 2-3' in height in cultivation but may reach 6' tall in moist cool climates in the wild. The showy parts of this fern are finely dissected, vegetative (sterile) fronds which, as the common name suggest, exhibit the feathery appearance of long ostrich plumes.
