Blechnum hastatum

A hardy terrestrial hard fern of central and southern Chile and adjacent Argentina, common on shaded banks, ravines and forest edges. It lives under a Mediterranean climate with warm dry summers and cool wet winters, so it takes cool nights and light frost but wants its roots kept moist in a shaded, sheltered spot.
