Southern Maidenhair Ferns (Adiantum capillus-veneris) are native ferns that grow 12 to 26 inches tall on thin, wiry stems with delicate leaves. They have a distinctive appearance, as their mid-green leaves hang from the stems have a zig-zag pattern and are glossy and dark in appearance, creating a mound with a delicate texture that sits above the thin, black stems. Northern Maidenhair Ferns (Adiantum pedatum), also native to North America, have a similar delicate appearance. However, they feature leaflets that the shape of the leaves is typically either wedge-shaped or rectangular, with outer tips that are lobed, and the leaflet veins divide by twos, forming a fan pattern.

Habitat Variations

The two species of Maidenhair Ferns also differ in their preferred habitats. Southern Maidenhair Ferns grow in light to full shade and require constant moisture. They are typically found in the mountains and piedmont regions. On the other hand, Northern Maidenhair Ferns can be found in a variety of habitats, including moist woodlands, rocky slopes, and shaded ravines.

Cultivation Requirements

When it comes to cultivating these two ferns, there are a few differences in their requirements:

  • Southern Maidenhair Ferns:
    • Light to full shade
    • Constant moisture
    • Rhizome division for propagation
  • Northern Maidenhair Ferns:
    • Partial to full shade
    • Well-drained, moist soil
    • Division or spores for propagation

In summary, Southern and Northern Maidenhair Ferns share certain similarities in their delicate appearance. However, they have physical differences, varying habitats, and cultivation requirements.
