Peacock Fern

Selaginella willdenowii

Selaginella willdenowii, commonly known as Peacock Fern, is a fern ally prized for its iridescent blue-green foliage. This plant is not a true fern but a spikemoss. The shimmering effect is caused by structural coloration, where light reflects off the leaf surface. It thrives in humid, shaded environments, mimicking its native rainforest habitat. While it can be grown indoors, maintaining the necessary humidity is crucial for its survival. People grow it for its unique and captivating foliage, adding a touch of exotic beauty to indoor spaces or terrariums. It is primarily an outdoor plant in tropical climates.

💡 Pro Tips For Comparing These Plants

Mimosa Pudica Care Tips

Mimosa pudica requires ample sunlight and well-draining soil. It's relatively easy to grow but needs consistent moisture and occasional fertilization. The main challenge indoors is providing enough light for optimal growth and sensitivity. It can become leggy if not given enough light.

  • Provide at least 6 hours of direct sunlight daily.
  • Water only when the top inch of soil is dry.
  • Fertilize regularly during the growing season.
  • Prune to maintain shape and encourage bushier growth.
  • Protect from drafts and sudden temperature changes.
❄️ Winter: Reduce watering frequency and avoid fertilizing during the winter months. Provide supplemental light if needed to maintain growth and sensitivity. Ensure temperatures remain above 15°C.
☀️ Summer: Water more frequently during the summer months, especially during hot weather. Provide partial shade during the hottest part of the day to prevent leaf scorch. Fertilize regularly to support active growth.

Peacock Fern Care Tips

Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.

How do I propagate Mimosa Pudica?

Mimosa Pudica can be propagated by seeds or stem cuttings.

Peacock Fern

What are the light requirements for Peacock Fern?

Peacock Fern requires bright, indirect light to maintain its vibrant color. Direct sunlight can burn its delicate fronds, causing them to turn brown and crispy. An east-facing window is ideal, providing gentle morning light. If placing it near a south- or west-facing window, use a sheer curtain to filter the light.

How do I care for Peacock Fern?

Peacock Fern thrives in bright, indirect light. Direct sunlight can scorch its delicate fronds. Maintain consistently moist soil, but avoid waterlogging. Water when the top inch of soil feels slightly dry. High humidity is crucial; aim for 60-80%. Use a humidifier, pebble tray, or group plants together to increase humidity.

How do I propagate Peacock Fern?

Peacock Fern can be propagated through division or by spores. Division is the easier method.
