Selaginella uncinata 'Peacock Moss'

The Iridescent Blue Clubmoss

Selaginella uncinata, commonly known as 'Peacock Moss', is a strikingly iridescent species of spikemoss, admired for its shimmering blue-green foliage. Native to humid subtropical regions, this low-growing, mat-forming plant thrives in terrariums, shaded gardens, and as an underplanting in tropical landscapes.

Distinctive Features:

• Delicate, feathery foliage that shifts between green and metallic blue, depending on light exposure.
• Spreading, creeping growth habit, forming a lush carpet of greenery.
• Prefers warm, humid conditions, making it ideal for terrariums and shaded indoor spaces.
• Non-flowering but produces spores, characteristic of the Selaginella genus.
• Highly sensitive to drying out, requiring consistently moist conditions.

Care Tips:

• Light: Thrives in bright, indirect light to deep shade. Avoid direct sunlight, which can scorch the delicate foliage.
• Water: Keep soil consistently moist but not waterlogged. It is intolerant of drying out.
• Humidity: Requires high humidity (above 60%) to prevent leaf desiccation. Ideal for terrariums or bathrooms.
• Media: Prefers well-draining, rich organic soil with good moisture retention, such as a peat-based mix.
• Temperature: Grows best in warm conditions between 18°C and 26°C, avoiding cold drafts and sudden temperature drops.
• Fertiliser: Apply a diluted liquid fertiliser every 4–6 weeks during the growing season for optimal health.
• Repotting: Rarely needs repotting; refresh the soil every couple of years if grown in containers.

Additional Notes:

• Excellent for closed terrariums, paludariums, and shaded greenhouse setups.
• Can be propagated through division, ensuring new growth quickly establishes.
• Best paired with moisture-loving plants like ferns and bromeliads.
• Not frost-tolerant; protect from cold weather if grown outdoors.
• May revert to a greener shade in lower light conditions.

Selaginella uncinata 'Peacock Moss' is a mesmerising plant, well-suited to those who appreciate unique foliage and high-humidity environments. Whether grown in a terrarium or as ground cover in a tropical garden, its iridescent hues bring an enchanting, almost otherworldly quality to any plant collection.
