Athyrium facts, a short list

Name – Athyrium filix-femina
Type perennial

12 to 16 inches (30 to 120 cm)
Exposure shade and part shade
Soil ordinary


Outdoors, often in forest underbrush, it makes for very easy care and growing.

Planting athyrium

Planting is either in fall or in spring but avoid frost spells and high temperatures.

For this, use adequate potting soil mixed into your earth and pour a bed of clay pebbles along the bottom to increase drainage.

  • If potted, repot in spring every 2 or 3 years with a pot that is slightly larger across each time.
  • This plant prefers shade to sun, which would either be too dry or too hot for it.

The propagation of athyrium is through crown division in spring.

Pruning and caring for athyrium

Cut dried or yellowed leaves as they die off, one at a time, but it’s ok if you don’t do this.

Apart from this, athyrium requires practically no care or maintenance.

In summer, you might mulch the base of the plant to keep the soil moist.

In winter, the foliage will disappear, but fear not: it will start growing back in spring. Athyrium is very hardy and resists the coldest of winters.

All there is to know about the athyrium

This lady fern has the rare trait of being very comfortable in dark forest settings at the foot of trees.

Once it has started growing somewhere, it is very difficult to tear it out because its roots are tightly welded to its growing medium.

Note that the darker the shade it is under, the slower its growth; but its leaves are then all the more beautiful.

Smart tip about athyrium

Both indoors in a pot and outdoors in the ground, avoid excessively sunny locations.
