Description

The Selaginella willdenowii is a striking terrarium plant, admired for its metallic, iridescent foliage that shimmers blue and turquoise under the right light. Despite often being called the “Peacock Fern,” it is not a true fern but a spikemoss, belonging to an ancient group of plants that thrive in moist, shaded environments.

This species forms a dense, creeping carpet of foliage, making it an excellent choice for use as a groundcover in terrariums and vivariums. It thrives in humid, consistently moist conditions with bright but indirect light. High humidity is essential to prevent drying and maintain its signature iridescent sheen.

Perfect for adding vibrant colour and a tropical feel, the Selaginella willdenowii is a fantastic choice for plant collectors and terrarium builders who want a showpiece groundcover with a prehistoric twist.
