All About Dryopteris Affinis: The Scaly Male Fern
I’m Ferb Vu, and I’m here to answer all your burning questions about the Dryopteris affinis, also known as the scaly male fern or golden-scaled male fern. This architectural wonder from the plant kingdom is a popular choice for gardeners seeking a touch of elegance and lushness.
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.
How to care for Dryopteris Affinis?

- 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.
Is Dryopteris Affinis Evergreen?
In mild climates, the Dryopteris affinis retains most of its fronds throughout winter, earning its semi-evergreen status. However, in colder regions, some dieback might occur.
Is Dryopteris Affinis Toxic?
While not deadly, the Dryopteris affinis contains compounds that can cause stomach upset if ingested. It’s best to keep it out of reach of pets and children.
How Fast Does Dryopteris Affinis Grow?

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.
