What is Dryopteris Affinis?
The Dryopteris affinis is a robust and semi-evergreen fern native to western and southern Europe, stretching to southwestern Asia. It thrives in moist woodlands with high humidity, making it a familiar sight in places like the British Isles and western France.
Imagine a rosette of finely cut, arching fronds gracefully radiating from a stout, erect rhizome. That’s the Dryopteris affinis in all its glory. These fronds, reaching lengths of up to 1.2 meters (almost 4 feet!), are a sight to behold. Young fronds boast a vibrant light green, maturing into a rich, verdant hue.
But the true showstopper lies in the golden scales – ramenta, to be precise – that densely cover the stems. These scales, a warm yellow-brown, add a touch of regality, making the fern a standout in any garden.

- Soil: Well-drained, moist soil rich in organic matter is key. Think composted bark or leaf mold for optimal results.
- Watering: Keep the soil consistently moist, but avoid waterlogging. Regular watering, especially during dry spells, is crucial.
- Fertilizer: A balanced, slow-release fertilizer applied in spring can give your fern a boost.
- Hardiness: The Dryopteris affinis is generally considered hardy to USDA zones 5-8. In colder regions, winter protection might be necessary.

Dryopteris Affinis vs. Dryopteris Filix-Mas
The Dryopteris affinis has a close cousin, the Dryopteris filix-mas, commonly known as the male fern. Here’s a quick comparison to help you tell them apart:
- Frond Color: Dryopteris affinis boasts a bright yellow-green hue when young, maturing to a rich green. Dryopteris filix-mas has a more consistent, deep green color.
- Scales: The Dryopteris affinis is easily identified by its prominent golden scales on the stems. Dryopteris filix-mas has fewer, less noticeable scales.
