Rhytidiadelphus squarrosus

Springy Turf Moss, Springy Turf-moss, Square Goose Neck Moss

A tough, adaptable moss with leaves that bend sharply outward from reddish stems, giving it a star-shaped look from above. This growth pattern is called squarrose, where the leaf tips flare at right angles from the stem. One of the most common lawn mosses in the UK, it tolerates a wide range of soil conditions from chalky to acidic. Its springy, upright habit and tolerance of moderate light and airflow make it a versatile carpet moss for both open and closed terrariums.
