Thick-stemmed Moss Plant Care
Rhodobryum roseum (Hedw.) Limpr.
Updated · Sources · How we source care data
Rhodobryum roseum, commonly known as rose moss, is a species of moss of the subclass Bryidae and family Bryaceae, found throughout most of the world in woods or sheltered grassy places. It rarely forms sporophytes and spore cases, and primarily reproduces vegetatively by stolons, horizontal stems that root at the nodes, resulting in populations of plants that are sterile or only female.

Replant every 1-2 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
How Do You Propagate a Thick-stemmed Moss?
Thick-stemmed Moss can be propagated through spores, division of clumps. Similar propagation techniques also apply to rhodobryum huillense plant care, which shares the same genus.
