We love this fantastic dense growing acid green moss. It finds its best home in containers- not quite tough enough for life in the ground. Slowly expanding rounded dense clumps are beautiful all the time. Excellent as the understory to potted plants where it inhabits the most constrained roots with no problem. To 3″ x 6″ in a season. Very easy container plant. Regular water in rich, well drained soil. Regular water. Smooth and modern.
