Video answer: Growing land moss underwater
Top best answers to the question «What type of moss can survive underwater»
A looot of terrestrial moss can survive underwater. I've tested dozens of varieties of moss myself. Typically, it won't survive if it can't grow "out" normally on land, ie, pollup type mosses, nub mosses, very short mosses. The types that do survive are those that can grow, almost any moss with vertical structure.
