Blechnum confluens

A terrestrial hard fern of moist forest in Colombia, Bolivia and Venezuela, recorded mostly around 900 m on the Andean slopes. Little is published on its ecology, so care follows the genus: warm, humid, bright shade and a constantly moist, acidic, free-draining soil.

Where it grows wild

Like most tropical Blechnum it grows on the ground or on banks in humid forest, along streams, trail cuts and forest edges, where light is broken rather than deep. Species-specific habitat notes were not found.

Records span 350–2778 m with a median of 900 m, so most plants grow in warm premontane forest; the highest records point to tolerance of cool nights.
