Selaginella uncinata, commonly known as Blue Spikemoss or Peacock Fern, is a captivating plant admired for its iridescent blue-green foliage. Despite its common names, it is neither a true moss nor a fern but a lycophyte, a more ancient group of vascular plants.
Here's a guide to keeping Selaginella Uncinata | Blue Spikemoss | Peacock Fern beauty thriving:
Light
Bright, indirect light is ideal. An east-facing window or a location with filtered light is perfect.
It can tolerate lower light conditions, and the blue coloration may even be more pronounced in slightly shadier spots.
Avoid direct sunlight, which can scorch its delicate leaves.
Watering
Requires consistently moist soil. Water when the top inch of the soil starts to feel slightly dry.
Water thoroughly, ensuring the pot has good drainage to prevent waterlogging and root rot. Never allow the plant to sit in standing water.
"Little and often" is a good approach. Be mindful not to let the soil dry out completely.
Reduce watering slightly in winter when growth slows, but never allow the soil to become bone dry.
Humidity
High humidity is crucial for Selaginella uncinata to flourish. Aim for humidity levels of 50% or higher.
Ideal for terrariums, which naturally provide a humid environment.
If not in a terrarium, increase humidity by:
Regularly misting the plant with a fine spray.
Using a pebble tray filled with water near the plant (ensure the pot isn't sitting directly in the water).
Grouping plants together to create a more humid microclimate.
Using a humidifier.
Temperature
Prefers moderate temperatures between 12-26°C (53-79°F).
Avoid extreme temperatures and drafts of hot or cold air.
Cannot tolerate temperatures below 10°C (50°F).
Soil
Needs a well-draining potting mix that also retains moisture.
A mix containing peat moss or coco coir, along with perlite or pumice for drainage, works well. A fern mix is also suitable.
Slightly acidic to neutral soil pH (around 5.5 to 7.0) is preferred.
Fertilizer
A light feeder. Fertilize sparingly, once a month during the spring and summer growing season with a diluted balanced liquid fertilizer.
Avoid over-fertilizing, which can lead to fertilizer burn.
No need to fertilize during the fall and winter when the plant is typically dormant or has significantly slowed growth.
Propagation
Can be propagated relatively easily by division or stem cuttings.
Division: Gently divide a mature plant into smaller sections, ensuring each section has its own root system, and replant them in fresh potting mix.
Stem cuttings: Take a 2-4 inch stem cutting, remove the lower leaves, and place it in moist potting mix or water until roots develop.
Additional Tips
Pruning: Trim away any brown or dead fronds to maintain the plant's appearance and encourage new growth.
Terrariums: Its love for humidity makes it an excellent choice for terrariums, where it can create a stunning blue-green carpet. Ensure good ventilation in enclosed terrariums to prevent excessive moisture buildup and fungal issues.
Color Intensity: The intensity of the blue coloration can vary depending on light conditions and the specific plant. Plants in slightly lower light may exhibit a more intense blue hue.
By providing the right conditions, your Selaginella uncinata will reward you with its unique and beautiful foliage for years to come.
