I bought a chunk of willow moss. Can I expect this to spread and become an actual carpet? Or what?
Maybe. Willow moss grows in cold and cool waters though. It is very commonly found moss where I live.
so willow moss is the same as weeping moss?
Someone misread the question and replied incorrectly.
Weeping moss scientific name is Vesicularia ferriei and Willow moss
scientific name is Fontinalis antipyretica
