Achillea vs Peacock Moss Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Achillea
Achillea millefolium
Achillea millefolium, commonly known as Yarrow, is a herbaceous perennial prized for its fern-like foliage and clusters of small, daisy-like flowers. Typically grown outdoors in gardens, it forms a spreading mat of aromatic leaves. The flowers, which come in shades of white, yellow, pink, and red, bloom from late spring to late summer. Yarrow is valued for its medicinal properties, drought tolerance, and ability to attract pollinators. It's primarily an outdoor plant and struggles indoors due to high light requirements.
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.

💧 Watering Needs
Achillea
Water deeply when the top inch of soil is dry. Avoid overwatering, as it can lead to root rot. Yarrow is drought-tolerant once established. Overwatering signs: yellowing leaves, wilting despite moist soil. Underwatering signs: dry, crispy leaves, stunted growth.
Peacock Moss
Keep the soil consistently moist but not waterlogged. Water when the top inch of soil feels slightly dry. Overwatering can lead to root rot, while underwatering will cause the foliage to dry out and turn brown. Use distilled or rainwater to avoid mineral buildup.

❓ Frequently Asked Questions — Comparing These Plants
Achillea
What are the light requirements for Achillea?
Achillea thrives in full sun, requiring at least 6-8 hours of direct sunlight per day. Insufficient light can lead to leggy growth, reduced flowering, and weaker stems. When planting, choose a location that receives ample sunlight throughout the day. In hotter climates, some afternoon shade may be beneficial to prevent scorching of the foliage. For indoor cultivation (less common but possible), provide the brightest possible light, ideally with supplemental grow lights. Rotate the plant regularly to ensure even exposure to light.
How do I care for Achillea?
Achillea is relatively low-maintenance, thriving in well-drained soil and full sun. Water regularly after planting to help establish the root system. Once established, Achillea is drought-tolerant and prefers infrequent, deep watering. Fertilize in spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage continued blooming throughout the summer. Divide clumps every 2-3 years in spring or fall to prevent overcrowding and maintain vigor. Achillea benefits from good air circulation to prevent fungal diseases. Avoid overwatering, especially in heavy clay soils. Mulch around the base of the plant to retain moisture and suppress weeds.
How do I propagate Achillea?
Achillea can be easily propagated through division, stem cuttings, or seeds.
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.
