Autumn Brilliance Fern
Dryopteris erythrosora 'Brilliance'
Autumn Brilliance Fern is a great fern when you want more than basic green texture in the shade garden. The coppery new fronds bring a warm glow in spring, then the foliage settles into a glossy green that works with almost any shade combination. I especially like it with hostas, heuchera, hellebores, astilbe, Mountain Laurel, and shaded evergreens, where the changing foliage color adds movement and polish without much maintenance.

Coppery Color for Elegant Shade Gardens
Copper-red new fronds with glossy green maturity.
Autumn Brilliance Fern produces striking new fronds in copper-red, orange-red, and copper-pink tones that gradually mature to glossy deep green. This seasonal color shift gives shaded gardens a lively, changing look without depending on flowers. The warm new growth stands out beautifully against dark mulch, stone, hostas, heuchera, hellebores, brunnera, astilbe, and other shade perennials, making this fern a standout accent for refined woodland designs.
A compact fern for layered shade plantings.
This Brilliance Autumn Fern forms a graceful arching clump that fits beautifully in shade borders, woodland gardens, foundation beds, and shaded entry plantings. Its fronds add soft texture without becoming too large or overwhelming nearby plants. Use it near the front or middle of a shade bed, repeat it in groups for a stronger foliage display, or tuck it around broadleaf evergreens and shade shrubs to create a polished layered planting.
Reliable color for woodland and foundation gardens.
Autumn Brilliance Fern is especially effective in woodland gardens, Japanese-inspired gardens, shaded courtyards, and foundation plantings where foliage texture matters as much as flowers. The coppery spring growth adds brightness early in the season, while the mature green fronds keep the bed full and fresh later in the year. It also works well as a companion to azaleas, rhododendrons, Mountain Laurel, hostas, carex, and other plants that enjoy cool, shaded garden conditions.
Deer-resistant foliage with low-maintenance appeal.
Autumn Brilliance Fern is commonly considered deer-resistant and rabbit-resistant, making it a practical foliage plant for shaded landscapes where browsing pressure can be frustrating. Once established, it is low maintenance and more adaptable than many delicate-looking ferns, tolerating average shade-garden conditions as long as the soil is not allowed to stay extremely dry. For best performance, give it part shade to full shade, organic soil, and consistent moisture.
Beautiful in containers and shaded outdoor living spaces.
Autumn Brilliance Fern also grows well in shaded containers, porch planters, and mixed patio pots where its coppery new growth can be appreciated up close. In containers, it pairs beautifully with heuchera, hostas, carex, begonias, caladiums, and other shade-loving foliage plants. Use it to soften shaded patios, entryways, and seating areas, or plant it in groups to create an elegant, low-maintenance fern display in the landscape.

How to Care for Autumn Brilliance Fern
Be sure to read our planting instructions to ensure a healthy and happy Autumn Brilliance Fern for years to come!
How should I plant Autumn Brilliance Fern?
Plant Autumn Brilliance Fern in part shade to full shade with loose, humusy, moist, well-drained soil. A site with morning sun and afternoon shade, filtered light, or bright open shade is ideal, especially in warmer climates where hot afternoon sun can stress the fronds. Dig a hole about twice as wide as the root ball and set the crown level with the surrounding soil. Backfill, water deeply, and space plants about 18 to 24 inches apart so the clumps have room to fill in while still creating a lush, layered shade-garden display.
How often should I water Autumn Brilliance Fern after planting?
Water Autumn Brilliance Fern regularly during the first growing season while the roots establish. Keep the soil evenly moist, especially during warm weather, dry spells, or the first several weeks after planting. Once established, Autumn Brilliance Fern prefers steady moisture but can tolerate short dry periods better than some moisture-loving ferns. If fronds brown, crisp, or fade quickly, dry soil, hot sun, or wind exposure may be the cause.
When should I fertilize Autumn Brilliance Fern?
Fertilize Autumn Brilliance Fern lightly in spring with compost, leaf mold, or a gentle organic fertilizer if the soil is poor. Rich organic matter helps mimic woodland soil conditions and supports strong foliage color. Avoid heavy fertilizer applications, which are usually unnecessary and can push soft growth. A yearly layer of compost or shredded leaf mulch helps feed the soil, conserve moisture, and keep the root zone cool.
When and how should I prune Autumn Brilliance Fern?
Prune Autumn Brilliance Fern by removing old, damaged, or winter-burned fronds in late winter or early spring before new coppery fronds begin to unfurl. Cut old fronds close to the base without damaging the crown. During the growing season, remove browned or damaged fronds as needed to keep the plant tidy. If the clump becomes crowded after several years, divide it in spring as new growth begins.
