Question for the group:

Considering all of the growing media variants out there, how many of those
materials actually support orchids in the wild?

Coconut husk No
Douglas Fir bark No
Cork Oak bark No
Charcoal No
Perlite No
Sphagnum Maybe some very wet growing terrestrials, but I don't know of
any
Osmunda (root system of the Osmunda cinnamomia fern)
Tree fern Yes! (sometimes)

Others?

Rock, sometimes.

I think you should probably rule out the materials that don't occur
naturally. Otherwise, we might ask whether flowerpots support orchids
in the wild. Perlite is mined, but expanded perlite that we use is
manufactured from the mined material.

Sphagnum Maybe some very wet growing terrestrials, but I don't know of
any

IIRC, Habenaria repens, Pogonia ophioglossoides, Arethusa bulbosa.
Probably some others.

Persimmon tree branches. Maybe, but the branches tend to be attached to
growing trees in the wild.

What about marshmallows?

I agree, but those came out before caffeine this morning. Charcoal also
fits the "non-natural" medium. Yes, it CAN be natural, but it would occur
so rarely that a plant growing on it would be by the slimmest of chances.

Cork Oak bark No
- Yes for the Australian Native Cork and some Sarco species and other small
epiphytes. I actually have used many this as a mount many times as I find it
lasts well and seems to support the small plants well.


Charcoal No
- In areas known for fire, many aussie native terrestrials require the
charcoal to be present to signify the presence of fire before they will grow
and flower. Also have seen plants growing on burnt trees in areas where the
charcoal is older than the plant.


Perlite No

Sphagnum Maybe some very wet growing terrestrials, but I don't know of
any
- Many Aussie natives will grow on Sphagnum. ( Rentouls "Growing Orchids"
has photos of this in the wild)


Osmunda (root system of the Osmunda cinnamomia fern)

Tree fern Yes! (sometimes)
- Quite a few tree ferns will support orchids as will some Cycad species.


Kye.

For many of the plants that we encounter in Australia, charcoal can be
considered a naturally occurring material. After all we are one of the few
places in the world that has evolved plant life to support fires and the
natural eco-system requires it for much propogation.

OK, but I've never seen persimmon anything sold as a medium...

I recall last year seeing some place selling/auctioning
off orchids mounted on persimmon branches.

But I could have crossed some wires upstairs and be misremembering
bromeliad supplies.

Completely and utterly off topic but...
Is the Australian Native Cork of the Quercus genus at all?

To my knowledge no its not. If you would like, I have a few botanist friends
that I can ask for confirmation...

No. It is --Erythrina vespertilio-- , a member of the family
Fabaceae.
