Brake Fern vs Peacock Moss Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Brake Fern
Pteridium aquilinum
Bracken fern is a large, coarse, deciduous fern characterized by its widely creeping rhizomes and erect, triangular fronds. It is one of the most widely distributed ferns in the world, thriving in diverse habitats from open woodlands to heathlands. Its fronds can reach impressive sizes, often exceeding 1 meter in height. While valued for its adaptability and soil-stabilizing properties in natural landscapes, it is generally not cultivated as an indoor plant due to its size, specific environmental needs, and potential toxicity. People may encounter it in the wild or in large outdoor gardens.
Peacock Moss
Selaginella willdenowii
Peacock Moss is a fern-like plant, though technically a spikemoss, known for its iridescent blue-green foliage. The leaves appear to shimmer with a metallic sheen, creating a rainbow effect in the right light. It's a low-growing, spreading plant that thrives in humid environments. While it can be grown indoors, it requires specific conditions to flourish, making it more challenging than many common houseplants. It is grown for its unique foliage and visual appeal.

💡 Pro Tips For Comparing These Plants
Brake Fern Care Tips
Bracken fern is primarily an outdoor plant and is challenging to grow indoors due to its size, light requirements, and aggressive spreading habit. It requires ample space, well-drained soil, and specific humidity levels. It is also toxic to pets, making it a less desirable indoor plant.
- Provide ample space for the plant to spread.
- Monitor for signs of rhizome rot and adjust watering accordingly.
- Control spread by using physical barriers or regular pruning.
- Fertilize sparingly, as bracken fern is adapted to nutrient-poor soils.
- Remove dead fronds in late fall or early spring to maintain a tidy appearance.
Peacock Moss Care Tips
Peacock Moss requires high humidity and consistent moisture, making it more challenging to grow indoors than many common houseplants. It thrives in terrariums or enclosed environments where humidity can be maintained. Proper lighting is crucial to maintain its iridescent color. It is not drought-tolerant.
- Maintain high humidity by misting regularly or using a humidifier.
- Use distilled or rainwater to avoid mineral buildup in the soil.

❓ Frequently Asked Questions — Comparing These Plants
Brake Fern
What are the light requirements for Brake Fern?
Brake Ferns require bright, indirect light to thrive. Direct sunlight can scorch their delicate fronds, causing browning and damage. The ideal location is near an east-facing window or a few feet away from a south- or west-facing window with sheer curtains to filter the light. Insufficient light can lead to leggy growth and pale foliage. If your fern isn’t getting enough natural light, consider supplementing with a grow light. Rotate the plant regularly to ensure even exposure to light, promoting balanced growth on all sides. Monitor the plant’s foliage for signs of light stress, adjusting its position as needed to maintain healthy, vibrant growth.
How do I care for Brake Fern?
Brake Ferns thrive in bright, indirect light and consistently moist soil. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain high humidity by misting regularly or using a humidifier. The ideal temperature range is between 65-75°F (18-24°C). Fertilize monthly during the growing season (spring and summer) with a diluted, balanced liquid fertilizer. Repot in spring every 1-2 years into a slightly larger pot with well-draining potting mix. Prune away any yellowing or dead fronds to encourage new growth and maintain a tidy appearance. Protect from drafts and sudden temperature changes. Monitor for pests such as mealybugs or scale and treat promptly if detected. Proper air circulation is essential to prevent fungal diseases.
How do I propagate Brake Fern?
Brake Ferns can be propagated through division or by spores. For division, carefully separate the rhizome into sections, ensuring each section has healthy fronds and roots. Plant each section in its own pot with well-draining potting mix. To propagate by spores, collect spores from mature fronds and sow them on a moist, sterile growing medium in a humid environment. Keep the medium consistently moist and provide bright, indirect light. Spores require patience as they take several weeks to germinate. Once small plantlets develop, transplant them into individual pots. Both methods are best done in spring. Ensure high humidity during propagation for best results.
Peacock Moss
What are the light requirements for Peacock Moss?
Peacock Moss requires bright, indirect light to maintain its vibrant coloration and healthy growth. Direct sunlight can scorch its delicate foliage, so it’s best to avoid placing it in a location where it will receive intense sun exposure. An east-facing window or a spot a few feet away from a south- or west-facing window is ideal. If the plant is not receiving enough light, its colors may become dull and less vibrant. Supplemental lighting, such as a grow light, can be used if natural light is insufficient. Rotate the plant periodically to ensure even light exposure on all sides. The goal is to mimic the filtered light conditions of its natural rainforest habitat.
How do I care for Peacock Moss?
Peacock Moss thrives in consistently moist, humid conditions. Water thoroughly when the top inch of soil feels slightly dry, using distilled or rainwater to avoid mineral buildup. Maintain high humidity by misting regularly, using a humidifier, or placing the plant on a pebble tray filled with water. Provide bright, indirect light, avoiding direct sunlight which can scorch the delicate foliage. The ideal temperature range is between 65-75°F (18-24°C). Plant in a well-draining, moisture-retentive potting mix such as a mix of peat moss, perlite, and vermiculite. Fertilize sparingly during the growing season (spring and summer) with a diluted liquid fertilizer. Prune any dead or yellowing fronds to encourage healthy growth. Regularly check for pests and address any infestations promptly. A terrarium is an ideal environment for this plant.
How do I propagate Peacock Moss?
Peacock Moss can be propagated through division or spores. For division, gently separate the plant into smaller clumps, ensuring each clump has healthy roots and foliage. Plant each division in a well-draining, moisture-retentive potting mix. Keep the divisions consistently moist and humid until they are established. Spore propagation is more challenging but can be achieved by collecting spores from mature fronds and sowing them on a sterile substrate. Maintain high humidity and provide indirect light. Division is the easier and more common method. Successful propagation requires patience and consistent care. Provide a warm and humid environment for best results.
