Adiantum poiretii

A widespread montane maidenhair found from Mexico and the Andes to tropical and southern Africa, Madagascar and southern India. It grows mostly at mid to high elevation (median about 2000 m) in cool, seasonally dry climates, typically on shaded banks, rock crevices and forest edges. It wants cool nights and bright shade, and tolerates a drier winter.

Where it grows wild

In its montane range it typically grows in moist crevices of rocks and walls, on shaded earth banks, along streams and at the edges of montane forest and scrub. Specific habitat notes were not in the sources checked, so this reflects the genus pattern for such highland species.

Recorded from 48 to 4500 m, median 2030 m (435 records); most records are montane.
