Thuidium tamariscinum

Common Tamarisk Moss, Tamarisk Thuidium Moss, Common Tamarisk-moss

A pleurocarpous moss — meaning it branches sideways rather than growing upright — with tri-pinnate, fern-like fronds that form green carpets on woodland floors. Native across Europe and parts of eastern Asia, it does best in cool, humid conditions. In a closed terrarium, its fine branching pattern creates a convincing miniature forest-floor layer.
