This primitive plant is celebrated for its intricate, feathery foliage that exhibits a remarkable iridescent blue-green shimmer, particularly when grown in shaded conditions.

Care Guide
Peacock Moss Care Guide
Lighting
Peacock Moss thrives in medium to bright indirect light. Direct sunlight should be avoided at all costs as it will quickly scorch the delicate fronds and cause the unique blue iridescence to fade into a dull green or brown.
Watering
This plant requires a consistently moist substrate. It has no drought tolerance; if the soil dries out, the plant will likely collapse. Water frequently to keep the soil damp but not soggy to prevent root rot.
Humidity
High humidity (70% or higher) is essential for Selaginella uncinata. It is an ideal candidate for terrariums, Wardian cases, or bathrooms with windows. In standard household environments, a humidifier or frequent misting is necessary.
Temperature
Maintain temperatures between 60°F and 80°F (15°C - 27°C). Protect it from cold drafts and sudden temperature fluctuations.
Soil and Potting
Use a moisture-retentive, peat-based potting mix with a bit of perlite or sand for drainage. Since it has a shallow root system, shallow pots or broad containers are preferable.
Common Issues
- Crispy Brown Edges: Usually caused by low humidity or dry soil.
- Loss of Blue Color: Often a result of too much light or high temperatures.
