Blechnum vieillardii

A New Caledonian endemic fern recorded from sea level to about 1,180 m, mostly in the hills of the main island. Treat it as a warm, humid forest-edge fern: bright shade, steady moisture and a lean, acidic, free-draining medium.

Where it grows wild

Little species-specific habitat detail is published; like many New Caledonian Blechnum it probably grows on banks and forest margins, including on ultramafic soils. Treated here as a terrestrial fern of humid forest and edges.

Recorded from 0–1180 m, median about 360 m.
