Parablechnum cordatum (syn. Blechnum chilense)

A robustly handsome South American evergreen fern producing very bold, very leathery, darkest green fronds with many broad, opposite pinnae. Slowly spreads to form patches, with fronds reaching about 1m, or up to 1.5m if moist and sheltered. Humus rich neutral to acid soil in shade, semi-shade, or sun if moist. Large clumps or drifts of this species is one of the most striking features of many Western seaboard garden in the British Isles, though hardy throughout the UK. Looks fabulous in Chile with Gunnera and Chusquea, etc.
