Peacock Fern, Blue Spike Moss

Easy careTerrestrialNon-toxic5–15 cm

A low, creeping plant with iridescent blue-green foliage that shifts colour depending on the angle of light. It is technically a lycophyte, not a true fern, though it looks and behaves like one. It needs very high humidity and consistent moisture, so it does best in a closed terrarium.
