Polypodium puberulum

A small, finely hairy polypody of Mexican pine-oak and cloud forest that grows on trunks and rocks at mid elevations. It expects a wet summer and a dry, cool winter, when its fronds can curl and wait for the rains; growers should mimic that rhythm rather than keep it soaked year round.

Where it grows wild

Records cluster on the humid slopes of Veracruz, Puebla, Oaxaca and Chiapas. Like related Mexican polypodies, it grows on mossy trunks, branches and rock faces in pine-oak and montane forest; this is inferred from the genus and range.

Recorded from 128 to 2,820 m, median about 1,900 m.
