Blechnum procerum

A small to medium hard fern endemic to New Zealand and its subantarctic islands, common on forest floors, banks and scrubby clearings from sea level to the subalpine zone. It is a cool-temperate plant: it wants mild, constantly moist, humid conditions and suffers in tropical warmth.
