Leucobryum glaucum
Cushion Moss
Grows in dense, rounded mounds that feel soft and spongy to the touch. Each cushion holds moisture well, which helps stabilise humidity in a closed terrarium. It does best in low indirect light and stays pale green to white-green when healthy.

Care
Prefers very high humidity, low light, with 15–24 °C, and reaches 5 cm at maturity.
