Which species will be good to hang in treers?

[epiphyte78]

There are hundreds of epiphytic orchid species that can handle growing outdoors in Sydney year around...dozens that could handle growing outdoors in the Blue Mountains and I certainly wouldn't be surprised if there were a few that could handle the Snowy Mountains. With around 20,000 species of epiphytic orchids it would be strange if there wasn't a reasonable amount of variation in cold tolerance.

Regarding orchids on trees...well...to each their own for sure. But when my visitors come over they are interested in seeing the garden. Since we're in the garden to begin with it's easy enough just to show them the orchids growing on my trees.
