- Description
-
The Southern Maidenhair is a deciduous, perennial fern in the Ribbon-fern family (Pteridaceae). It is native to temperate and tropical regions worldwide. The genus name comes from the Greek word adiantos, meaning “unwetted,” in reference to the water-repellent foliage. The specific epithet comes from Latin meaning hair (capillus) of Venus (veneris) and is reflected by its other common name, Venus maidenhair fern.
The fern spreads by short, creeping rhizomes and prefers moist, humus-rich, alkaline to neutral soil in partial shade to shade. It needs 12 inches to 3 feet of planting space and grows about 10 inches to 2 feet high and wide. It is low maintenance but requires moist but not saturated soil and fertilizer, especially when potted. This fern is listed as Endangered in North Carolina due to loss of habitat.
The Southern Maidenhair fern can be grown almost anywhere that provides suitable conditions. This includes containers, native gardens, woodlands, and shade gardens.
Quick ID Hints:
- Fronds twice-compound, membranous

- Pinnules triangular, lobed
- Sori marginal covered by revolute marginal flap
- Stipe & rachis wiry, black
Insects, Diseases, and Other Plant Problems:
No significant problems. The Florida Fern Caterpillar can be a problem.
