: Like all ferns, it reproduces via spores rather than seeds. These spores appear as small black spots (sori) clustered on the underside of the leaflet margins, often protected by the reflexed edge of the leaf tissue—a characteristic known as a "false indusium".

It thrives in high humidity and bright, indirect light, making it a popular indoor or greenhouse plant in cooler climates. It is hardy only in USDA zones 9 and above and must be protected from frost. It is one of the few indigenous pteridophytes

: Primary dangers include habitat fragmentation due to residential and tourism development, which destroys the specific cave-mouth and rocky woodland environments it requires. Invasive species like Cyrtomium falcatum (Holly Fern) also compete for its limited ecological space.
