Autumn Fern Plants | Dryopteris erythrosora, Copper-Toned Foliage

Bring warm color to a shady garden with autumn fern, Dryopteris erythrosora. Young fronds emerge in coppery-orange tones before maturing to rich green, creating a layered display of color and texture. Plant beside a shaded path or group in a woodland-style border where the changing foliage can be enjoyed up close.

Planting

Choose a sheltered, shaded position with loose, humus-rich soil and good drainage. Set the crown at its existing soil level rather than burying it deeply. Space approximately 20–24 inches apart and water thoroughly after planting. For containers, use a pot with drainage holes and a moisture-retentive, well-drained growing mix.

Care

Keep soil evenly moist while plants establish, avoiding prolonged waterlogging. A light mulch helps conserve moisture; keep it away from the crown. Protect from harsh afternoon sun and drying winds. Remove damaged or old fronds as needed without disturbing emerging growth.

Garden uses

Use in shaded borders, woodland gardens, or containers for foliage interest rather than flowers. Pair with other shade-loving plants to contrast their leaf shapes with the fern’s finely divided fronds. Winter appearance and cold tolerance depend on local conditions; check regional planting guidance before choosing a permanent outdoor location.
