Dried out 'all of the above....roots, leaves, stems.' Dry and dead. It is long lasting and expensive. Orchids grow well on it or in it.

Thanks for the inside info on the mounts, jane_ny. (I know from posts elsewhere, that you've been a successful orchid grower from the North down to the South :)

shavedmonkey, yes that's the type of live ones I kept finding in photos. (and presumably can grow well in your 10b)

It can grow here. It grows robustly on the floor of the tropical rainforests. Here, with constant care it will grow.

Hi

Don't confuse "Tree fern mounts with Long fibered Sphagnum moss The mounts are the trunks of tree ferns compressed and formed into various shapes usually for the purpose of growing epiphytes ,mostly orchids .

I've used them for many years in the form of pots,sheets even in the shape of bunnies lol I grow 5 kinds of tree ferns but have had no luck getting orchids to grow on the living ferns .Interestingly they produce a fiber that repels epiphytes from attaching . Dead ,the orchid will happily grow right into it.

They discourage the use of tree fern mounts because they have wiped out whole forests harvesting them for that purpose.

If you want to mount orchids use cork bark works as well and is a renewable resource. though if growing indoors would think a poor choice ?? gary
