Autumn Fern Dryopteris erythrosora 'Brilliance'
ABOUT
The Dryopteris erythrosora 'Brilliance', commonly known as the Autumn Fern, is a visually striking plant that exhibits a vibrant array of colors throughout its fronds. As the name 'Brilliance' suggests, this fern is celebrated for its lustrous and bright foliage. Young fronds unfurl in a striking copper-red to pink shade, providing a splash of color that resembles the hues of autumn leaves. As the fronds mature, they transition through a sequence of colors, eventually settling into a deeper green. The fern's leaves are divided into numerous leaflets, imparting a feathery texture that adds to its visual interest and elegance. The leaflets delicately line the arching fronds, giving the fern a full and lush appearance, which can add a touch of natural flamboyance to shaded garden areas or indoor spaces. Its evergreen nature ensures that it provides year-round interest, with the changing colors of the fronds marking the passing seasons. The combination of its changing palette and graceful form make the Autumn Fern a beloved addition to many gardens and indoor plant collections.

- Water
The Autumn Fern should be watered thoroughly once a week, allowing the soil to slightly dry out between waterings. In higher heat or during dry spells, increase watering to twice a week ensuring the soil is moist but not waterlogged. Depending on the pot size, watering with about 16 to 24 ounces of water should be sufficient each time. During the winter months, reduce the watering frequency to every other week as the plant's growth slows and it requires less moisture.
- Light
Autumn Fern thrives in partial to full shade, making it ideal for a spot that receives filtered sunlight or dappled shade. Avoid placing it in direct sunlight as the leaves can get scorched. A north-facing window or a shaded area in a south-facing room is often a great spot for this plant.
- Temperature
The Autumn Fern prefers temperatures between 60 and 75 degrees Fahrenheit. It can tolerate a minimum temperature of 50 degrees Fahrenheit but avoid exposing it to temperatures below this, as it can cause damage to the plant. The fern does not thrive in temperatures above 80 degrees Fahrenheit, so keep it away from heat sources and areas that can get excessively hot during summer months.
- Pruning
Pruning the Autumn Fern isn't regularly necessary, but it's beneficial to remove any brown or damaged fronds to keep the plant looking tidy. The best time for pruning is in spring before new growth begins. Gently cut away the old fronds at the base without disturbing the younger, green fronds. This helps to redirect the plant's energy to new growth and can improve air circulation.
- Cleaning
As needed
- Soil
Autumn fern prefers well-draining, rich, loamy soil with a pH of 5.0 to 6.0. A mix with one part garden soil, one part peat moss, and one part perlite or pine bark is ideal for maintaining moisture while allowing excess water to drain, providing the acidity and organic matter that this fern thrives on.
- Repotting
Autumn ferns should be repotted every 2-3 years to refresh the soil and give the roots more space to grow. The best time to repot is in early spring before new growth begins.
- Humidity & Misting
Autumn ferns prefer high humidity levels, ideally between 60% to 70%. In drier environments, it is beneficial to increase humidity around the plant through misting or using a humidifier.
- Suitable locations
Indoor
Place in diffused light; keep soil moist but not soggy.
Outdoor
Partial shade; protect from afternoon sun and wind.
Hardiness zone

- Life cycle
The Autumn Fern 'Brilliance', Dryopteris erythrosora 'Brilliance', begins life as a spore, which germinates in moist, shaded conditions to establish a small, heart-shaped gametophyte. The gametophyte produces both male and female reproductive structures and, once fertilization occurs, gives rise to a new diploid sporophyte—the leafy fern plant we recognize. This fern emerges in spring with fiddleheads that unfurl into vibrant, colorful fronds with hues of orange, copper, and red, before maturing to a deep green. Throughout the growing season, the fern increases in size and may produce new fronds from the center of the plant. As a perennial, the Autumn Fern dies back in the winter, with the fronds becoming dormant and withered, to return again the following spring from the same root system. Over years, the plant can form a large, dense clump, and it may be divided to propagate new plants and maintain vigor.
- Propogation
Propogation time
Spring-Early Summer
The popular method for propagating the Autumn Fern, scientifically known as Dryopteris erythrosora 'Brilliance', is through spores, which is best done in summer when they are ripe and ready. To propagate, one should collect fertile fronds that have ripe spore cases on their undersides and place them inside a paper bag. Allow the fronds to dry, which will cause the spores to be released into the bag. Then, the spores can be sown on the surface of a fine-textured, sterile potting mix. The potting container should be covered with plastic wrap to maintain a high humidity level and placed in a warm area with indirect sunlight. Germination takes quite a while, typically several weeks to months, and it's important to keep the soil consistently moist and to avoid direct sunlight that could scorch the tender young ferns. Once the sporelings are large enough to handle, they can be transferred to individual pots to grow on before planting out.
