Peacock Moss vs Polypody Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
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.
Polypody Fern
Polypodium virginianum
Polypodium virginianum, commonly known as Rock Polypody, is an evergreen fern typically found growing on rocks and tree trunks in moist, shaded environments. It features creeping rhizomes that anchor it to its substrate, from which arise deeply lobed, leathery fronds. These fronds are typically 10-30 cm long and have a distinctive, somewhat glossy appearance. While primarily an outdoor plant, it is sometimes grown indoors, though replicating its natural environment can be challenging. People grow it for its unique appearance and ability to thrive in rocky or woodland gardens. It is not a fast grower.

❓ Frequently Asked Questions — Comparing These Plants
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.
Polypody Fern
What are the light requirements for Polypody Fern?
Polypody Ferns prefer bright, indirect light. Direct sunlight can scorch their delicate fronds, causing them to turn brown and crispy. An east-facing window is often ideal, providing gentle morning light. A north-facing window can also work well, although the light may be less intense.
How do I care for Polypody Fern?
Polypody Ferns thrive in bright, indirect light; avoid direct sunlight, which can scorch their delicate fronds. Water consistently, keeping the soil consistently moist but not waterlogged. Use well-draining potting mix to prevent root rot. Aim for high humidity levels, ideally above 60%; mist regularly or use a humidifier.
How do I propagate Polypody Fern?
Polypody Ferns can be propagated through division or spores. Division is the easier method. To divide, carefully remove the fern from its pot and gently separate the rhizomes into smaller sections, ensuring each section has healthy fronds and roots. Plant each section in its own pot with well-draining potting mix. Keep the soil consistently moist and provide high humidity until new growth appears.
