Description

The Peacock Spike Moss ( Selaginella uncinata ) is a dazzling terrarium favourite, admired for its iridescent foliage that shimmers with blue-green and bronze hues depending on the light. Despite its name, it is not a true moss or fern, but a primitive plant that creates lush, carpet-like growth, perfect for terrariums and vivariums.

This species thrives in humid, shaded environments with evenly moist, well-draining soil. It is best kept in enclosed or high-humidity terrarium conditions, where its delicate foliage can maintain vibrancy and avoid drying out. Its creeping growth habit makes it ideal for creating dense understorey carpets or adding a splash of shimmering colour to naturalistic setups.

A favourite among collectors and terrarium builders alike, the Peacock Spike Moss is as hardy as it is beautiful, making it suitable for both beginners and advanced hobbyists.
