Description and General Information:
Fragile fern is one of the few species of plants that is found worldwide. Within North America, it is found throughout except for the southeastern States. It is a relatively small, tufted species with brittle, deciduous fronds arising from a thickish rhizome. The stipe is smooth and slender, up to 10 centimetres long. Fronds may reach to 40 centimetres long and 6 centimetres wide on robust plants but are more often closer to 20 centimetres and narrower. It most commonly grows as a lithophytic species, tucked in the cracks of crevices of cliffs and talus slopes. It is found as commonly on acidic rock as basic.
Cultivation:
Fragile fern requires a shady, cool location and even moisture. If too dry, plants will go dormant. Best to plant on the north side of a rock, especially in a narrow crack if possible. Plants are shallow-rooted and prefer an organic-based media that is not too wet or dry. Soil pH is not an issue.
Blooming Period:
Not applicable
Propagation:
Spores, division
Seeds:
Spores may be dusted on surface of an organic mix. Keep at room temperature and cover container to maintain 100% humidity. Spores sown in autumn will be small plants by late spring.
Division:
Plants may be dug and divided just as the new fronds emerge in spring. Take care as new fronds are very fragile.
