Adiantum sulphureum
A maidenhair of central and southern Chile and adjacent Argentina whose frond undersides carry pale yellow farina, which gives it the name. The measured sites have a Mediterranean climate with a long rainless summer and cool, wetter winters. It is best grown cool and bright with dry-ish summers and more water in winter.
Where it grows wild
Detailed habitat notes were not in the sources checked. In central Chile it grows in shaded rock crevices, on moist banks and in ravines where some moisture persists into the dry summer. This is inferred from the climate and related farinose species.
Recorded from 200 to 1576 m, median 1000 m (24 records).
