Blechnum tomentosum

A little-documented terrestrial Blechnum known only from a handful of Bolivian records around 1,540–1,600 m in the Yungas. Treat it as a warm-montane forest fern: bright shade, steady moisture, mild days and cool nights, with a drier but still humid winter.

Where it grows wild

Records sit at 1,539–1,600 m (median 1,600 m).
