About Autumn Fern
Autumn Fern (Dryopteris erythrosora) is an evergreen to semi-evergreen fern valued for its arching fronds, soft texture, and distinctive coppery-red new growth that gradually matures to glossy green.
Unlike many plants with “Autumn” in the name, Autumn Fern is not primarily known for fall color. The name refers to the warm bronze, copper, and reddish tones that appear on newly emerging fronds.
Its refined foliage makes it especially useful in shade gardens, woodland-style landscapes, courtyards, foundation beds, and mixed plantings where customers want year-round or near-year-round texture without relying on flowers.
Outdoor Warehouse Supply carries Autumn Fern in both 1-gallon and 3-gallon containers year-round.

Common Names Associated with Autumn Fern
This plant is commonly known as:
- Autumn Fern
- Japanese Shield Fern
- Copper Shield Fern
Its botanical name is Dryopteris erythrosora.
For the customer-facing product title, Autumn Fern is the strongest and most recognizable name.
Growth Habit & Mature Size
Autumn Fern forms a compact clump of arching fronds, usually reaching approximately 18–24 inches tall and wide.
Its habit is full and layered rather than upright and rigid, giving it a softer appearance in the landscape.
Because it stays relatively compact, it works especially well in:
- Front and middle sections of shade beds
- Foundation plantings
- Courtyard gardens
- Woodland-style landscapes
- Mixed fern groupings
- Containers
Plant Spacing & Common Planting Patterns
Spacing Autumn Fern approximately 18–24 inches apart gives each plant enough room to develop into a full clump.
Closer spacing can create a denser massed effect, while wider spacing allows the form of each plant to remain more visible.
Common planting patterns include:
- Mass fern plantings
- Shaded borders
- Woodland gardens
- Foundation beds
- Courtyards
- Understory plantings
- Containers
- Mixed shade gardens
Sun, Soil & Water Requirements
Autumn Fern performs best in partial shade to full shade.
Filtered light or morning sun can be tolerated, but intense afternoon sun can scorch foliage, especially during North Texas summers.
The plant prefers moist, rich, well-drained soil.
Consistent moisture is beneficial, particularly during establishment and periods of summer heat.
Autumn Fern should not be allowed to remain continuously waterlogged, but it also performs poorly when subjected to prolonged drought.
Is Autumn Fern Evergreen or Deciduous?
Autumn Fern is generally considered evergreen to semi-evergreen.
In mild winters, much of the foliage may remain attractive throughout the year.
Hard freezes can damage or brown older fronds, especially in exposed locations.
Fresh fronds typically emerge again as temperatures warm.
For North Texas, it is best described as evergreen to semi-evergreen depending on winter severity.
Growth Rate & Lifespan
Autumn Fern has a moderate growth rate.
Once established, it gradually develops into a dense clump rather than spreading aggressively.
With proper shade, moisture, and drainage, it can remain in the landscape for many years.
Its clumping growth habit makes it easier to control than more aggressively spreading groundcovers.
Copper, Bronze & Red New Growth
One of Autumn Fern’s most distinctive features is its newly emerging foliage.
Young fronds can display shades of:
- Copper
- Bronze
- Reddish-orange
- Rust
- Warm pinkish-bronze
As the fronds mature, they gradually transition to glossy green.
This changing foliage color gives Autumn Fern much more seasonal interest than a typical all-green fern.
Autumn Fern for Shade Gardens
Autumn Fern is especially useful for creating texture and foliage contrast in shaded landscapes.
It pairs well with plants such as:
- Holly Fern
- Fatsia Aralia
- Soft Caress Mahonia
- Heuchera
- Ajuga
- Hostas in protected areas
- Other shade-tolerant shrubs and perennials
Its coppery new growth can also contrast especially well against darker green evergreen shrubs.
Autumn Fern in Containers
Autumn Fern can also perform well in containers.
Its compact size and arching foliage make it suitable for:
- Shaded patios
- Courtyard pots
- Entry planters
- Mixed shade containers
Containers should have adequate drainage and receive regular irrigation during warm weather.
