Adiantum bellum

Bermuda maidenhair fern

Bermuda's only native maidenhair: a small fern with fan-shaped, light to mid-green fronds 5–30 cm long on shiny black stalks. It grows in shaded, moist but well-drained places on the island's limestone, in rock crevices, on cliffs, under ledges, on roadside verges and on hillsides. It is a good subject for a shaded, humid terrarium or a sheltered, bright-shade spot in frost-free areas.

Where it grows wild

Shaded, moist sites on Bermuda: crevices, cliffs and the undersides of rock ledges, roadside banks and hillsides, and near water where the ground drains well. Bermuda's rock is limestone, so the fern grows on lime-rich substrates.

Bermuda rises only to about 76 m, so all sites are near sea level; the records carry no elevation.
