Hardy Plumbago vs Peacock Moss Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Hardy Plumbago
Plumbago auriculata
Plumbago auriculata, commonly known as Cape Plumbago, is a sprawling, semi-woody shrub prized for its clusters of phlox-like, sky-blue flowers. It's primarily an outdoor plant, thriving in warm climates. It can grow to a considerable size if left unchecked. People grow it for its vibrant flower color, drought tolerance, and ability to attract butterflies. While it can be grown in containers, it requires significant pruning and may not flower as profusely indoors. It is not naturally an indoor plant.
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.

❓ Frequently Asked Questions — Comparing These Plants
Hardy Plumbago
What are the light requirements for Hardy Plumbago?
Hardy Plumbago thrives in full sun to partial shade. Ideally, it should receive at least six hours of direct sunlight per day for optimal flowering. In hotter climates, providing some afternoon shade can prevent scorching of the leaves. When grown indoors, place it near a sunny window where it can receive ample light. Insufficient light can lead to reduced flowering and leggy growth. Rotate the plant regularly to ensure even light exposure on all sides. Monitor the plant for signs of light stress, such as pale leaves or elongated stems. Adjust its location accordingly to provide the appropriate amount of light.
How do I care for Hardy Plumbago?
Hardy Plumbago thrives in well-drained soil and requires regular watering, especially during dry periods. Plant in a location that receives full sun to partial shade; more sun promotes more blooms. Fertilize in the spring with a balanced fertilizer to encourage healthy growth and flowering. Prune in late winter or early spring to remove dead or damaged growth and to maintain the desired shape. Hardy Plumbago is relatively pest and disease-resistant but monitor for common garden pests. Mulch around the base of the plant to help retain moisture and suppress weeds. Deadhead spent flowers to encourage continued blooming. Protect from frost in colder climates, as it is only hardy to USDA zones 5-9. Regularly check soil moisture and adjust watering as needed. Proper drainage is essential to prevent root rot. Provide support if needed, as the plant can sometimes sprawl.
How do I propagate Hardy Plumbago?
Hardy Plumbago can be propagated by division, stem cuttings, or root cuttings. For division, carefully dig up the plant in early spring or fall and separate the root ball into smaller clumps. Replant the clumps in well-drained soil. For stem cuttings, take 4-6 inch cuttings from new growth in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist until they root. For root cuttings, take 2-3 inch sections of root in late winter. Place horizontally in a tray of compost and cover lightly. Keep moist until new growth appears. These will need warmth to be successful.
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.
